Indicate that a process has stopped by setting PS_STOPPED flag
The checks in dowait6 and orphanpg using ps_mainproc are flawed and
fail if the mainproc called pthread_exit before the other threads.
Adding the flag in proc_stop_sweep is racy but the best we have right now.
This fixes regress/sys/kern/signal/sig-stop3.
