[PATCH v4] Tests for pthread_getcpuclockid method. Ticket:3891

The patch is the test for pthread_getcpuclockid.
The patch will not run since there is no support for pthread_cpuclockid in clock_gettime function
the patch compiled with no errors
It is tested against the patch https://lists.rtems.org/pipermail/devel/2020-March/058176.html
Can you all review it and check if it is logically correct?
and what changes are required for it to be pushed
thanks:)

+Directives:
+ Pthread_getcpuclockid()
+
+Concepts:
+
++ 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.
