On second thought, remove regex.linux.utf8 regression test altogether.

The code-coverage report says that this test doesn't increase
coverage by one single line, which I now realize is because
I made src/test/modules/test_regex/sql/test_regex_utf8.sql
to cover all the code that this would.  So really it's pointless
and we should just drop it.
