thread_pthread.c: use CLOCK_REALTIME on SunOS (Solaris)

Browse source 
timer_create does not seem to support CLOCK_MONOTONIC on Solaris,
and CLOCK_HIRES seems like it could fail with insufficient permissions:

https://docs.oracle.com/cd/E86824_01/html/E54766/timer-create-3c.html

(Only tested on Linux and FreeBSD)
