xboxdrv: upgrade the build process to python3

Python3 is the default in current Debian & friends distros, but the current fork from zerojay/xboxdrv.git doesn't support it.

Upstream has moved back to Github [1] and added the necessary fixes for building with `python3`, so merge the upstream code with the various fixes added in zerojay/xboxdrv under retropie/xboxdrv.git. This fixes building under RaspiOS _bullseye_.

Since the new Sconsfile doesn't build with `python2` anymore, make the `python3` usage explicit for the `deps` and `build` phases.
