pw: Ensure group membership is not duplicated
Fix the following problem:
1. A nonexistent user, someuser, is added to somegroup in /etc/group.
2. someuser is then created with membership in somegroup.
The entry for somegroup in /etc/group will then contain
somegroup:*:12345:someuser,someuser
With this fix, the entry will be
somegroup:*:12345:someuser
