daemon: Remove the 'NIX_SUBSTITUTERS' environment variable.
* nix/libstore/globals.cc (Settings:update): Remove changes to 'substituters'. * nix/nix-daemon/guix-daemon.cc (main): Set 'settings.substituters' directly instead of changing the 'NIX_SUBSTITUTERS' environment variable. * build-aux/pre-inst-env.in: Remove reference to 'NIX_SUBSTITUTERS'.
