remove source ghcjs, the nixpkgs patch has been merged

[makoConstruct]

in shell.nix there is

        # Can be dropped when nixpkgs includes
        # https://github.com/NixOS/nixpkgs/pull/177489/files
        # Keep synced with kaleidogen for better cache usage!
        ghcjs-base = super.ghcjs-base.overrideAttrs(d: {
          src = pkgs.fetchFromGitHub {
            owner = "ghcjs";
            repo = "ghcjs-base";
            rev = "fbaae59b05b020e91783df122249095e168df53f";
            sha256 = "sha256-x6eCAK1Hne0QkV3Loi9YpxbleNHU593E4AO8cbk2vUc=";
          };
        });

It seems like that time has come.

(Tragically, I only noticed this after spending 3 hours compiling ghcjs from source)

Thanks! Have you tried this already?

[makoConstruct]

No, haven't gotten around to it

[makoConstruct]

Alas. I commented out the ghcjs base source part, now nix-shell errors with complaints about a missing aeson. I don't know what that is, but it's already being included in two different parts of the nix expression, so I'm at a complete loss.
