Remove race in enewuser, enewgroup
We had an obvious TOCTOU problem in enewuser and enewgroup.
The code would check to see if a user or group was already
created early in these functions, then do a bunch of work
and check again. If the account was created in the meantime,
it'd barf on the second check. This check is redundant anyway
so remove it.
