Some Zig applications like `ncdu` requires extra information like `zig.meat.platforms` and `zig.hook`

[Ziqi-Yang]

ncdu in nixpkgs
zig in nixpkgs

I need to do this to make my configuration work:

  zig = final: prev: let
    # ncdu requres zig.meta and zig.hook
    meta = prev.zig.meta;
    # though zig version of zig.hook still refers to the original zig.
    passthru = prev.lib.getAttrs ["hook"] prev.zig.passthru;
  in rec {
    zig = inputs.zig-overlay.packages.${final.system}.master.overrideAttrs (f: p: {
      passthru = passthru;
      meta = meta // inputs.zig-overlay.packages.${final.system}.master.meta;
    });
    zls = inputs.zls.packages.${final.system}.default;
  };
