This test fails intermittently in systems with heavy load as CLOCK_PROCESS_CPUTIME_ID is subject to scheduler pressure. Thus the test boundaries were relaxed to keep it from failing on such systems. A refactor of the spent time checking was made with some support functions. With the advantage to representing time jitter in percent of the target. The values used by the test boundaries are all empirical. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
