IPA: properly handle mixed-case trusted domains

In the SSSD cache domain names are handled case-sensitive. As a result
fully-qualified names in RDN contain the domain part in the original
spelling. When IPA client lookup up group-memberships on the IPA server
via the extdom plugin the names returned are all lower case. To make
sure new DNs are generated correctly the domain part must adjusted.
