tst_wiringrules: skip the --run checks on a build without scripting

The project's CI builds QElectroTech without scripting, where --run is
not an option and the process never exits, so the test waited out its
timeout and failed (#1272's stack, CI run 37118548599). The --run checks
now skip there, as the script tests are left out of such builds; the
rules and the save round trip still run.
