Qyriad 3ac2dd0613 package: put boehmgc patch logic in package.nix
In our view it really doesn't make sense to not have this in in
package.nix in some way. These patches aren't just for performance or
something -- Lix flat out doesn't build without these patches.

(Arguably that makes them a buildsystem responsibility as well, but that
can wait for when we're ready to start adding subproject fallback
dependency resolution to Meson.)

This is a step towards making `package.nix` more self-sufficient and
`callPackage`able without excessive external logic.

With this change the following command is enough to build Lix from out
of the flake:

nix-build -E 'let pkgs = import <nixpkgs> { }; in pkgs.callPackage
./package.nix { build-release-notes = false; inherit (pkgs.lib) fileset;
nix-doc = pkgs.callPackage ./nix-doc/package.nix { }; }'
