IPA: Include SYSDB_OBJECTCATEGORY, not OBJECTCLASS in cache search results
The function get_object_from_cache() returns an ldb_message that is
passed to apply_subdomain_homedir() which expects SYSDB_OBJECTCATEGORY
to be present in the message, otherwise it errors out.
However, get_object_from_cache() was reading only SYSDB_OBJECTCLASS.
This patch changes get_object_from_cache() to ready
SYSDB_OBJECTCATEGORY.
