pgsql: AdjustUpgrade.pm should zap test_ext_cine, too.

AdjustUpgrade.pm should zap test_ext_cine, too.

test_extensions' test_ext_cine extension has the same upgrade hazard
as test_ext7: the regression test leaves it in an updated state
from which no downgrade path to default is provided. This causes
the update_extensions.sql script helpfully provided by pg_upgrade
to fail. So drop it in cross-version-upgrade testing.

Not entirely sure how come I didn't hit this in testing yesterday;
possibly I'd built the upgrade reference databases with
testmodules-install-check disabled.

Backpatch to v10 where this module was introduced.
