Time::HiRes contains code to emulate clock_gettime on Darwin, which
historically has not included that function. Most of this is guarded
by #ifdefs which check for both Darwin and the absense of clock_gettime.
However, the latter isn't applied consistently, resulting in build
errors on Darwin versions which include a native clock_gettime.

The attached patch fixes this by adjusting one #ifdef.
