move clock_gettime calls outside of setjmp context for NO_FORK mode

move clock_gettime calls outside of setjmp context for NO_FORK mode

The test duration was getting smashed if tests failed in NO_FORK
mode. If the setjmp() function was used to abort a test, the end
time would not get captured. This resulted in arbitrary numbers
being written for the test's duration.

This change moves the settime() calls outside of the setjmp() context,
so the times get captured if the test passes or fails.
