* When killing a build hook, kill the entire process group (as

  intended).  This ensures that any ssh child processes to remote
  machines are also killed, and thus the Nix process on the remote
  machine also exits.  Without this, the remote Nix process will
  continue until it exists or until its stdout buffer gets full and it
  locks up.  (Partially fixes NIX-35.)
