mkosi/kodi: don't rely on udev to discover joysticks

SDL prefers relying on udev events to discover and register new
joysticks. However inside the container, udev isn't running. We have
mounted /run/udev, but it seems that this is not sufficient.

As a workaround, tell SDL to prefer a fallback method of discovering new
joysticks.
