Don't process DNSSEC-related and ZONEMD records in catz

When processing a catalog zone update, skip processing records with
DNSSEC-related and ZONEMD types, because we are not interested in them
in the context of a catalog zone, and processing them will fail and
produce an unnecessary warning message.
