testing/ltp: Skip the CPU-time tests without the CPU-time clocks.
NuttX has the CPU-time clocks (CLOCK_PROCESS_CPUTIME_ID and
CLOCK_THREAD_CPUTIME_ID) only with the run-time accounting of the
critical section monitor (CONFIG_SCHED_CRITMONITOR_MAXTIME_THREAD >= 0).
Without it, <unistd.h> defines _POSIX_CPUTIME and _POSIX_THREAD_CPUTIME
as -1 (apache/nuttx#21146), and the LTP tests of these options print
"unsupported" or "not supported" instead of a result. Do not build them
then, as for the
other options that a configuration does not have.
