od: Fix sdl2 joystick translator driver
Browse files Browse the repository at this point in the history 
1. Add `JoystickGetDevicePath` needed from SDL2 2.23.1.
   See libsdl-org/SDL@e551384

2. Update the GUID using the scheme required from SDL2 2.25.1.
   See libsdl-org/SDL@c1e0873

3. Run autogen.sh for the new `--enable-joystick-translator`
to be supported.
