selftests/cgroup: add user_usec sanity check in test_cpucg_nice
In test_cpucg_nice, after the child process exits, user_usec is
read from cpu.stat but the value is not checked. Add a sanity check
to ensure user_usec > 0, analogous to test_cpucg_stats(), so that
the test fails early if CPU usage wasn't properly accounted.
