Josh Siviour 7bcd365549 ci(eks-ami): build on self-hosted ci-single runner (#326)
* ci(eks-ami): build on self-hosted ci-single-1 runner

GitHub-hosted ubuntu-24.04 cannot run the libguestfs appliance network:
passt fails (PID file denied under its AppArmor confine / privilege drop)
and the SLIRP fallback has no outbound, so virt-customize --network dies.
The self-hosted ci-single-1 runner has /dev/kvm and real networking, so
the existing libguestfs build works unmodified.

* fix(build-system-image): add --no-cache, force fresh build on publish

The <10min cached-raw skip avoids duplicate work for concurrent e2e
jobs, but on the persistent publish runner it could republish a stale
image from a prior or concurrent run. Add --no-cache to bypass the skip
and have publish-system-image.sh pass it on every build.

* ci(eks-ami): target ci-single label (no ci-single-1 label exists)

The self-hosted runners are named ci-single/-2/-3 but all share the
single label 'ci-single'; runs-on matches labels, not names, so
ci-single-1 never schedules.

* ci(eks-ami): disable Go cache on self-hosted runner

setup-go's cache-save (Post Setup Go) re-uploaded the Go cache to the
Actions backend on every run, taking ~2.5min vs the 36s build. The
self-hosted runner already keeps the cache on local disk, so cache:false.

name: Publish EKS node AMI
# Builds the eks-node system AMI (libguestfs, on the runner) and publishes the
# compressed qcow2 + .sha256 sidecar to the Cloudflare R2 bucket that backs
# iso.mulgadc.com/system-ami/. Operators then install it on any cluster with:
# spx admin images import --name spinifex-eks-node
#
# Manual-only: publishing overwrites the mirror artifact, so it is a deliberate
# action, not something every push should trigger.
