Improve stability of identity.sql regression test. I noticed while trying to run the regression tests under a low geqo_threshold that one query on information_schema.columns had unstable (as in, variable from one run to the next) output order. This is pretty unsurprising given the complexity of the underlying plan. Interestingly, of this test's three nigh-identical queries on information_schema.columns, the other two already had ORDER BY clauses guaranteeing stable output. Let's make this one look the same.
Back-patch to v10 where this test was added. We've not heard field reports of the test failing, but this experience shows that it can happen when testing under even slightly unusual conditions.
