test: make test_omp_get_wtime deterministic - #77

The busy-wait asserted elapsed time within 5 ms (places=2). CI runner preemption past the deadline failed the macOS job intermittently. Timing accuracy belongs to libomp, not PyOMP. Keep binding coverage: omp_get_wtime is the only float64-returning _OpenmpExternalFunction, so the test checks a positive float from both njit and interpreted calls.

test_omp_get_wtimebusy-waited for 0.25 s. It then asserted the elapsed time withassertAlmostEqual(delay, t, places=2), which allows only 5 ms of error. The loop cannot exit early, so the only possible error is overshoot. On shared CI runners, the process can be descheduled for more than 5 ms near the deadline. This made the macOS job fail intermittently.The test no longer measures time. It now checks that
omp_get_wtimecan be called from njit code and from interpreted Python, and that each call returns a positivefloat.
