Subject: [PATCH] pythonPackages.wrf-python: Fix build (#56989)

The latest changes to support better cross-compilation compatibility
have introduced a stricter handling of dependency specification in
python. Since b4acd977, gfortran should be put into nativeBuildInputs,
as it's a build-time only dependency for wrf-python. Similarly, mock is
only required when testing, so it should go to checkInputs.
