Stabilize repack_decode isolation test.
Commit 7164dcb66532 added the repack_decode isolation test, whose
s1_decode step counts every change decoded from the slot. A concurrent
autovacuum transaction that modifies only system catalogs is decoded
as an empty BEGIN/COMMIT pair, so the count could come out larger
than expected.
Fix by passing skip-empty-xacts to test_decoding. We pass it, along
with include-xids=0, to s1_decode_updates as well so that both steps
use the same options for consistency, though that step shows only
UPDATE lines and wasn't affected.
