killUser: Don't let the child kill itself on Apple
The kill(2) in Apple's libc follows POSIX semantics, which means that kill(-1, SIGKILL) will kill the calling process too. Since nix has no way to distinguish between the process successfully killing everything and the process being killed by a rogue builder in that case, it can't safely conclude that killUser was successful. Luckily, the actual kill syscall takes a parameter that determines whether POSIX semantics are followed, so we can call that syscall directly and avoid the issue on Apple.
