Fix broken CREATE RULE test in appendonly and aocs regression tests.

The tests were added in commit 7d0325e4
and were not properly translated from Pivotal's internal tests to the
pg_regress tests. They now properly test CREATE RULE on AO/CO tables.

Thanks to Heikki Linnakangas for catching this issue.
