Allow clock_gettime() monotonic clock to be utilized on more OS's

Allow the clock_gettime() code using monotonic clock to be utilized on
more POSIX compliannt OS's. This started as a fix for OpenBSD which was
listed in one function as part of the previous hard coded list of OS's
for the functions to support but not in the other.
