dsdb: Ensure "authenticated users" is processed for group memberships

This change moves the addition of "Authenticated Users" from the very end of the
token processing to the start.  The reason is that we need to see if
"Authenticated Users" is a member of other builtin groups, just as we
would for any other SID.  This picks up the "Pre-Windows 2000 Compatible Access"
group, which is in turn often used in ACLs on LDAP objects.

Without this change, the eventual token does not contain S-1-5-32-554
and users other than "Administrator" are unable to read uidNumber
(in particular).
