repo/commit: Support group-writable files for bare-user-only

These exist in the wild for flatpak, and aren't really a problem. The canonical
permissions are still either `0755` or `0644`, we just support the additional
writable bit for the group (i.e. extend the set to include `0775` and `0664`)
now to avoid breaking some flatpak content.

Closes: #913
