[PATCH 3/8] drm/sched: Reduce scheduler's timeout for timeout tests

As more KUnit tests are introduced to evaluate the basic capabilities of
the `timedout_job()` hook, the test suite will continue to increase in
duration. To reduce the overall running time of the test suite, decrease
the scheduler's timeout for the timeout tests.
