workflows/testsuite.yaml - Add testing of -DNO_TAINT_SUPPORT

Test that we can pass test with -DNO_TAINT_SUPPORT but without
-DSILENT_NO_TAINT_SUPPORT. Both disable taint mode, but the latter
causes -t and -T to be silently ignored, whereas the former by itself
causes use of -t and -T to throw fatal exceptions during process
startup.
