useradd_base: keep group if it still has users

perform_groupdel() tries to delete a group irrespective if other
users have it as their primary group, thus the call to groupdel will
fail with the following error error:

groupdel: cannot remove the primary group of user '<user>'

Add a check to perform_groupdel() to determine if there are other
users and keep the group, printing a warning. This is called right
after a user is deleted to delete it's group. If the last user is
deleted, only then the group is also deleted.
