feat(wpcarro/emacs): Package emacs GUI for OSX

Did a little reverse-engineering to try and figure out how to package GUIs for
OSX, which where I learned about:
- `Info.plist`
- `version.plist`
- `pkgs.lib.generators.toPlist`

I'm sure there is more to do to make idiomatically pkg this, but this is enough
to get started, and I need to move-on.
