test_must_fail: use test_match_signal

In 8bf4bec (add "ok=sigpipe" to test_must_fail and use it to fix flaky tests, 2015-11-27), test_must_fail learned to recognize "141" as a sigpipe failure. However, testing for a signal is more complicated than that; we should use test_match_signal to implement more portable checking.
