Does it need matplotlib during build-time (e.g. because some kind of extension module needs to be compiled? Or can the same functionality be obtained by simply adding matplotlib to the runtime closure afters in python.withPackages?

@FRidh binwalk and binwalk-full currently are not exposed via all-packages.nix, and only live in the python package set. I think it's fine for now to just add it to propagatedBuildInputs.
