[dwm] patch to not reparent children to init

Reparenting everything to init with the double-fork is a nightmare on a
many-user machine, especially when I'm logged in more than once. pstree
becomes useless. This sets up a SIGCHLD handler and only forks once.
Adds 2 SLOC, but surely there's some reason the double-fork is there that
I'm just missing...

sigchld(int signal)
  while (0 < waitpid(-1, NULL, WNOHANG));

spawn(const Arg *arg)
  signal(SIGCHLD, sigchld);
  if (fork() == 0) {
    if (dpy) close(ConnectionNumber(dpy));
    execvp(((char **)arg->v)[0], (char **)arg->v);
    fprintf(stderr, "dwm: execvp %s", ((char **)arg->v)[0]);
    perror(" failed");
