[PATCH v3] Tests for pthread_getcpuclockid method. Ticket:3891

Hello,
As Dr Joel suggested
I have added the .5 seconds cpu time delay on the clock id of the thread and calculated the
wall time using CLOCK_REALTIME but this will return error as there is no support for
CLOCK_THREAD_CPU_TIME_ID.
If we use CLOCK_REALTIME then it returns the time in nanoseconds.
Also I didn't know what changes to make to the .scn file since the time can change for different
architectures.
I request everyone to have a look at it.

thanks
Eshan

++ This test exercises the getcpuclockid methods.
+
++ For pthread_getcpuclockid it created a pthread using pthread_create and
+ then finds the clockid_t of that thread then used gettime() add a pause of .5 seconds
+ and then ends the thread.
+ After the thread is ended it again tried to find the clockid_t of the thread to
+ check for ESRCH exception.
