Make a derivation for a Kicad plugin

the missing python bindings have been gnawing at me since i saw #40835 11 days ago

i kinda had to package the dependencies of kikit because i couldn’t think of another addon to try
i’d probably not submit those without figuring out their checkPhases

if this works i’d open a PR with those changes in hopes of getting someone with python/python bindings know-how to review it
i’m in doubt about this working, i’m not familiar with kicad plugins, and this one doesn’t appear to be detected
i just tried running kicad from the shell defined in derivation i posted and it seems to be missing the wrapping (so it’s getting the bin/kicad from kicad.base aka kicad.py instead of the wrapped one from pkgs.kicad)
