The change from https://github.com/grafana/loki/pull/12019/files cascaded into other usage of
EnsureDirectory
and thus required every place it was called to require at least0o700
permissions, effectively breaking any read-only mounts.I've separated creation from permissions testing so they can be applied independently, added some more utilities, and some testware.
