Each AFS cell has it's own set of user IDs that is uses internally, in its
ACL system and in its protection management protocol. The user ID used by
the fileserver is selected from the set belonging to the fileserver's cell
according to the authentication token associated with an RPC operation -
and this is set as a file's user ID when it is created.
This means that tests that expect to set a UID and see the same UID still
set afterwards will fail.
Add a "_require_use_local_uidgid" clause to indicate that a test expects
internal UID/GID information to be seen in the stat output and should be
skipped if AFS's case.
