tests: drop FAIL_TEST

Nothing is using FAIL_TEST or FAIL_TEST_P and that is good. Remove them to not
encourage using them.

If we need a test that should fail, it always needs to fail in a very specific
way which needs to be checked. For this we have e.g. expect_protocol_error().
We never want a fail-test to pass because it failed in a way we did not expect.
Therefore these macros are useless.
