sigprocmask-tests: skip test if pid is unexpectedly large
At least mingw64 has 8-byte pid_t but only 4-byte long. Silent truncation to int in printing a pid value with %d risks killing the wrong process. But rather than try to futz with determining the maximum pid_t, it is simpler to just cap things by realizing that this test is already skipped on mingw64, so adding a sanity check bounds comparison (and hard-coding the result rather than dragging in headers for INT_MAX) is just as effective at avoiding theoretical problems with no real loss in test coverage. * tests/test-sigprocmask.c (main): Add range check.
