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 89faa5c75cb3a419c6d02c51f56955275b7ae351, '--no-substitutes' would lead to attempts to use 'download-using-manifests.pl', which in practice would gracelessly fail.
