AD: filter domain local groups for trusted/sub domains
In Active Directory groups with a domain local scope should only be used
inside of the specific domain. Since SSSD read the group memberships
from LDAP server of the user's domain the domain local groups are
included in the LDAP result. Those groups should be filtered out if the
domain is a sub/trusted domain, i.e. is not the domain the client
running SSSD is joined to.
The groups will still be in the cache but marked as non-POSIX groups and
no GID will be assigned.
