upstream: Since the previous commit, ssh regress test sftp-chroot was

failing. The sftp program terminated with the wrong exit code as sftp called
fatal() instad of exit(0).  So when the sigchld handler waits for the child,
remember that it was found.  Then don't expect that main() can wait again. OK
