runtime(syntax-tests): Re-introduce support for "phoney" languages
As of patch v9.1.1176~1, there are no longer makeshift Make
targets to accommodate language names that can match phoney
targets. For example, "clean_" was previously generated for
Clean because otherwise it clashed with the "clean" target.
Additionally, enable test filtering for makeshift targets.
