This appears to be an issue with the patches to shadow for subuid/subgid
support.  The --{add,del}-sub{uid,gid}s options don't operate on
/etc/passwd, only on /etc/sub{uid,gid}; but the code causes usermod to
fail if called for any non-local user.

Assuming there's no policy reason why non-local users are disallowed
from /etc/sub{uid,gid}, this is a simple fix.  Cc:ing Serge Hallyn for
comment, as he originally pulled these patches in.
