lib.callPackageWith: Use resolveDefaultNix

Tested with:
1. Replace the callPackageWith call by `null`, to simulate an ancient Nix
2. Run the following commands in a terminal in nixpkgs:

    $ mkdir test/

    $ echo '{ asdfasdfasdf }: null' >test/default.nix

    $ nix repl -f .

    nix-repl> callPackage ./test { }
    error:
          … while calling the 'abort' builtin
            at /home/user/src/nixpkgs/lib/customisation.nix:312:7:

                |       ^
              313|

          error: evaluation aborted with the following error message: 'lib.customisation.callPackageWith: Function called without required argument "asdfasdfasdf" at /home/user/src/nixpkgs/test/default.nix'
