Try again to make QDeadlineTimer test robust against context switches

Instead of comparing to absolute values, compare the result from
QDeadlineTimer with the reference clock types from std::chrono. Pass
the test as long as we are within 10% of that reference.

In addition, handle the case where QTest::qSleep sleeps for more than
10% longer or shorter than what is requested, and if so, abort the
test.
