[Patch] Fix 'make bench' on MIPS where HP_TIMING_AVAIL is not defined

[Steve Ellcey]

I just tried running 'make bench' to do some performance testing on MIPS
and it failed because CLOCK_PROCESS_CPUTIME_ID was not defined in 
benchtests/bench-timing.h.  I fixed this by including time.h in the
section of code that gets compiled when HP_TIMING_AVAIL is not defined
(or USE_CLOCK_GETTIME is defined).

I was then able to run 'make bench'.  OK to checkin?
