sysdb: remove ghosts in all sub-domains as well

If a user is a member is a group in a different sub-domain, e.g with
universal groups in AD, the ghost attribute might not be properly
removed from the group object if the user is resolved. The reason is
that only groups from the domain of the user were search for ghost
attributes. This patch increases the search-base to all sub-domains of
the configured SSSD domain.
