Subject: [PATCH] Use upstream nixpkgs' packages-config.nix (#405)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The files in nixos-search and nixpkgs have already unnecessarily
diverged — more than they should given that the only difference is that
the search ignores unfree packages (while nixpkgs includes them for the
benefit of repology).

Since we update the NIX_PATH when calling nix-env in nixpkgs_info.rs, we
can simply import the packages-config.nix from nixpkgs using that
information and update it with our addition `allowUnfree = false`.

Fixes #337.
