daemon: Clear $NIX_SUBSTITUTERS when passed '--no-substitutes'.

* nix/nix-daemon/guix-daemon.cc (main): When --no-substitutes is used,
  clear NIX_SUBSTITUTERS.  Before that, and after
  89faa5c75c, '--no-substitutes' would
  lead to attempts to use 'download-using-manifests.pl', which in
  practice would gracelessly fail.
