Siddhesh Poyarekar 19a198f058 pthread_getcpuclockid: Add descriptive comment to smoke test
Add a descriptive comment to the tst-pthread-cpuclockid-invalid test and
also drop pthread_getcpuclockid from the TODO-testing list since it now
has full coverage.

/* The input thread descriptor to pthread_getcpuclockid needs to be valid when
the function is called. For the purposes of this test, this means that the
thread should not be detached, have exited, but not joined. This should be
good enough to complete coverage for pthread_getcpuclockid alongside
tst-clock2. */
