test: wait for cloned thread to exit
In test_raw_clone, make sure the cloned thread calls _exit() and in the parent thread call waitpid(..., __WCLONE) to wait for the child thread to terminate, otherwise there is a race condition where the child thread will log to the console after the test process has already exited and the assertion from the child thread might not be enforced. The absence of this patch might also create problems for other tests that would be added after this one, since potentially both parent and child would run those tests as the child would continue running. Tested by confirming that the logs from the child are printed before the test terminates and that a false assertion in the child aborts the test with a core dump. [zj: also add check for the return value.]
