refactor: stop running kodi in cage

Since cage 0.2.1 Kodi didn't work anymore. With 0.2.1 it crashed
which was fixed but with the fix Kodi still gives a black screen,
which I reported as https://github.com/cage-kiosk/cage/issues/469.
To keep it working I've been pinning cage to 0.2.0.

This bug still hasn't been fixed in cage 0.3.0. Now I want to upgrade
to NixOS 26.05 but that doesn't package wlroots 0.18 anymore
(which is needed by cage 0.2.0). Apparently Kodi can run standalone
without a display server, so let's just do that.
