IMPALA-6155: Allow tests to pass when ORDER BY does not cover the query.
Use VERIFY_IS_EQUAL_SORTED tag on RESULTS section to allow low-order
sort deviations to compare.
Testing:
- Passed local tests/run-tests.py ...
- Changed order of expected rows by low-order column and verified test
still passes.
- Analyzed all TPC-DS query files for similar patterns, found no others.

> in those columns, so the results would be valid if returned in either order.
> I'm surprised that this hasn't been flaky but it could hit us at any time.
