lib: use test failure status for igt_set_timeout

Use a failure status code for timeout to avoid confusion between tests
that take too long to execute versus a failure due to an operation
taking longer than expected.

v2: Add a "timed out" message before exiting. (Daniel Vetter)
    Fix the timeout library check by disabling hard errors in xfail
    tests, since these share the same exit status as test failure.
