upstream: Avoid kill with -1 argument. The out_ctx label can be
reached before fork has been called. If this happens, then kill -1 would be called, sending SIGTERM to all processes reachable by the current process. From tobias@ and c3h2_ctf via github PR#286, ok djm@ OpenBSD-Commit-ID: 6277af1207d81202f5daffdccfeeaed4c763b1a8
