Subject: [PATCH 1/2] Pull nixpkgs as tarball from channels.nixos.org

Actually working solution for https://github.com/NixOS/flake-registry/pull/61.
Don't even ask what "exact" is doing here, but it's load-bearing for this to
work. Stuff like `nix flake metadata nixpkgs/nixos-26.05` uses the channel tarballs,
while `nix flake metadata nixpkgs/master` falls back to `github:nixos/nixpkgs/master`.

Subject: [PATCH 2/2] Disable sortedness check

Registry resolution algorithm is order-dependent, and to get the desired
behavior with nixpkgs the indirect entry to `github:nixos/nixpkgs`
should come after all other exact entries.
