test: exercise the sqlite plugin in make test

TestSQLitePlugin has never run. It stats a flat bin/sqlite.so, which no
build target produces (make plugin_sqlite writes bin/linuxamd64/sqlite.so,
xgo writes bin/sqlite-linux-amd64.so), so it always took the skip branch.
Even past that it needs a seeded database, and nothing in the repo seeds
one.

seedplugindb stages the plugin at the path the test and
sample-database.cfg both expect, then starts glauth once so the plugin's
CreateSchema builds the tables before inserting rows. Taking the schema
from the plugin rather than duplicating its DDL here keeps the two from
drifting.

Guarded on bin/sqlite-linux-amd64.so existing, so CI - which never builds
plugins - still skips the test exactly as before.

+# Contributing to GLAuth
+
+Thanks for your interest in improving GLAuth! This guide covers how to set up your environment, submit changes, and work with the maintainers. Starting with GLAuth 2.4.0, we reworked and optimized the build workflow, and this contribution process reflects that.
+
+## Getting Started
+
+1. Fork the repository and clone your fork locally.
+2. Review the [Building](https://glauth.github.io/docs/building.html) docs to compile GLAuth from source.
+3. Review the [Testing](https://glauth.github.io/docs/testing.html) docs to run the test suite before submitting changes.
+4. Create a topic branch for your work off of `master`.
+
+## Reporting Issues
+
+- Open an issue on the [GLAuth issue tracker](https://github.com/glauth/glauth/issues) for bugs and feature requests.
+- Include your GLAuth version, configuration (with secrets redacted), and clear steps to reproduce.
+
+## Preparing to Commit
+
+Format your code automatically using `gofmt -d ./` before committing. If you forget this step, a subsequent pull request may fail.
+
+## Writing Commit Messages
+
+Commit messages must be semantically correct. We follow [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/).
+
+A commit message contains a prefix, followed by a short explanation. It may also contain "footer" annotations, but these are not mandatory (though appreciated).
+
+Please don't bundle multiple unrelated items in the same commit (e.g., a new feature and a bug fix).
+
+### Commit Prefix
+
+A prefix is written imperatively, for example:
+
+```
+feat(plugins)!: Change the plugins API to allow NoSQL databases.
+```
+
+This is a new feature (`feat`), optionally scoped to an area of GLAuth (`(plugins)`), with `!` warning of a breaking change.
+
+A more innocuous change:
+
+```
+chore: Add more comments in all modules.
+```
+
+Available prefixes: `feat`, `fix`, `chore`, `build`, `ci`, `perf`, `refactor`, `test`, `style`.
+
+### Commit Footer Annotations
+
+For example:
+
+```
+Reviewed-by: John Romero <john@romero.com>
+Tested-by: Joel Spolsky <joel@joelonsoftware.com>
+BREAKING-CHANGE: I broke the plugin

-This is a modified and opinionated fork of https://github.com/BurntSushi/toml with the following changes 
-
-- time.Duration is always encoded as a string ("10s" or "10ns")
-- support encoding comments (similar functionality to https://github.com/pelletier/go-toml.v1)
-  - comments can be added using the comment tag `comment:"a well thought-out comment"`
-  - valid toml can be commented out using the commented tag `commented:"true"`
-- Only guarantees last two years of golang compatibility (1.10 to current)

-## TOML parser and encoder for Go with reflection
-
-TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
-reflection interface similar to Go's standard library `json` and `xml`
-packages. This package also supports the `encoding.TextUnmarshaler` and
-`encoding.TextMarshaler` interfaces so that you can define custom data
-representations. (There is an example of this below.)
-
-Spec: https://github.com/toml-lang/toml
-
-Compatible with TOML version
-[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
-
-Documentation: https://godoc.org/github.com/BurntSushi/toml
-
-Installation:
-
-```bash
-go get github.com/hydronica/toml
-```
-
-Try the toml validator:
-
-```bash
-go get github.com/hydronica/toml/cmd/tomlv
-tomlv some-toml-file.toml
-```
-
-### Testing
-
-This package passes all tests in
-[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
-and the encoder.
-
-### Examples
-
-This package works similarly to how the Go standard library handles `XML`
-and `JSON`. Namely, data is loaded into Go values via reflection.
-
-For the simplest example, consider some TOML file as just a list of keys
-and values:
-
-```toml
-Age = 25
-Cats = [ "Cauchy", "Plato" ]
-Pi = 3.14
-Perfection = [ 6, 28, 496, 8128 ]
-DOB = 1987-07-05T05:45:00Z
-```
-
-Which could be defined in Go as:
-
-```go
-type Config struct {
-  Age int
-  Cats []string
-  Pi float64
-  Perfection []int
-  DOB time.Time // requires `import time`
-}
-```
-
-And then decoded with:
-
-```go
-var conf Config
-if _, err := toml.Decode(tomlData, &conf); err != nil {
-  // handle error
-}
-```
-
-You can also use struct tags if your struct field name doesn't map to a TOML
-key value directly:
-
-```toml
-some_key_NAME = "wat"
-```
-
-```go
-type TOML struct {
-  ObscureKey string `toml:"some_key_NAME"`
-}
-```
-
-### Using the `encoding.TextUnmarshaler` interface
-
-Here's an example that automatically parses duration strings into
-`time.Duration` values:
-
-```toml
-[[song]]
-name = "Thunder Road"
-duration = "4m49s"
-
-[[song]]
-name = "Stairway to Heaven"
-duration = "8m03s"
-```
-
-Which can be decoded with:
-
-```go
-type song struct {
-  Name     string
-  Duration duration
-}
-type songs struct {
-  Song []song
-}
-var favorites songs
-if _, err := toml.Decode(blob, &favorites); err != nil {
-  log.Fatal(err)
-}
-
-for _, s := range favorites.Song {
-  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
-}
-```
-
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
-
-```go
-type duration struct {
-	time.Duration
-}
-
-func (d *duration) UnmarshalText(text []byte) error {
-	var err error
-	d.Duration, err = time.ParseDuration(string(text))
-	return err
-}
-```
-
-### More complex usage
-
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
-  # You can indent as you please. Tabs or spaces. TOML don't care.
-  [servers.alpha]
-  ip = "10.0.0.1"
-  dc = "eqdc10"
-
-  [servers.beta]
-  ip = "10.0.0.2"
-  dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
-  "alpha",
-  "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
-	Title string
-	Owner ownerInfo
-	DB database `toml:"database"`
-	Servers map[string]server
-	Clients clients
-}
-
-type ownerInfo struct {
-	Name string
-	Org string `toml:"organization"`
-	Bio string
-	DOB time.Time
-}
-
-type database struct {
-	Server string
-	Ports []int
-	ConnMax int `toml:"connection_max"`
-	Enabled bool
-}
-
-type server struct {
-	IP string
-	DC string
-}
-
-type clients struct {
-	Data [][]interface{}
-	Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_examples/example.{go,toml}`.
