test-pressure: set timeout to make not wait forever

If this runs on a slow or busy machine, then we may not get enough
pressure to trigger the event sources. In such case, the test does not
finish. It is problematic when the test is _not_ run with 'meson test',
e.g. debian/ubuntu CIs.

Let's introduce a timeout for each event loop, and skip test cases
gracefully.
