Add allow_world_readable_secrets option to config file

Sometimes, the secret files permissions checks gets in the way. It's
by no mean complete, it doesn't take the Posix ACLs into account among
other things. Correctly checking the ACLs would be too involving (see
https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/658#issuecomment-7102)
and would likely still fail in some weird chmod settings.

We're adding a new configuration file key allowing the user to disable
this permission check altogether.

The (already existing) env variable counterpart always take precedence
to this config file option. That's useful in cases where the
configuration file is static and cannot be easily altered.

### `allow_world_readable_secrets`
Garage checks the permissions of your secret files to make sure
they're not world-readable. In some cases, the check might fail and
consider your files as world-readable even if they're not. Such as
when using Posix ACLs.
Setting `allow_world_readable_secrets` to `true` bypass this
permission verification.
Alternatively, you can set the `GARAGE_ALLOW_WORLD_READABLE_SECRETS`
environment variable to `true` to bypass the permissions check.
