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'.
