Removing usage_vs_refs from comparison gnu test suite

[ChrisDryden]

This test checks that all of the options are included in the GNU documentation, our implementation has a bunch of options that are not included and the test does not provide much value for us for regression purposes

I'd like to keep them as failing test at CI log.
If they produce big logs, you can symlink false to test files instead of sed.

LGTM — this test can never pass for uutils since we intentionally have different options (e.g. clap -V). Good riddance.

GNU testsuite comparison:

Skip an intermittent issue tests/pr/bounded-memory (fails in this run but passes in the 'main' branch)
Skip an intermittent issue tests/tail/tail-n0f (fails in this run but passes in the 'main' branch)
Skipping an intermittent issue tests/date/date-locale-hour (passes in this run but fails in the 'main' branch)
Note: The gnu test tests/cp/link-heap is now being skipped but was previously passing.
Congrats! The gnu test tests/expand/bounded-memory is now passing!
