id: support numeric lookup.
Fall back to converting the "name" to an integer and calling getpwuid(). We need to update `username` for the later call to getgrouplist(). Also fix the separator printing logic to avoid a trailing ',' on `id 0`. Switch to FLAG() and move some declarations down to where they can be initialized, both for clarity. Also add simple tests. Sadly, there's no always-present user that is in multiple groups.
