Negative tests can be expressed as a single parameterized test case,
which highlights that we're following the same test logic (passing
invalid cmdline and expecting drm_mode_parse_command_line_for_connector
to fail), which improves readability.
v2: s/negative/invalid to be consistent with other testcases in DRM
