Subject: [PATCH] Check that existing catalog zone entries are preserved

Update the 'catz' system test by adding tests that update an
catalog zone (catalog1.example) while preserving existing entries
(increase SOA serial) then check that catalog zone has transferred
and that the existing entries have not accidentally been removed
as a consequence (can return updated zone content).
