nsswitch: Fix wbcListUsers test

With an AD DC, wbcListUsers returns the users in the DOMAIN SEPARATOR
USERNAME format.  The test then calls wbcLookupName with the domain name
and the previous string (including domain and separator) as username.
Fix this by passing the correct username and adding some additional
checks.
