`nix (build|shell) mach-nix#gen` is broken on recent nix versions because of https://github.com/NixOS/nix/issues/6690. This commit fixes it by removing `meta` from the list of handled packages. As a result, nix can access the derivation's meta as expected, and work as expected. The side effect is that the `meta` package on pypi cannot be used, but that's a cost we have to pay.
