CTest: Improve stop-time implementation

The CTestTestStopTime test has been failing sporadically because the
stop time causes the first internal test to have a timeout short enough
that we might hit it and start the second test just before the stop time
is reached.  Instead we should track when a timeout is shortened in
order to stay within the stop time.  If a test times out for this reason
then we should consider the stop time reached and not start any more
tests.
