Subject: [PATCH] Initialize udev before joystick manual scan so class lookup
 works

LINUX_JoystickInit does a manual scan first so devices are sorted.
If SDL_UDEV_Init hasn't run by then, then the product info cannot
be looked up by SDL_UDEV_GetProductInfo and the initial-plugged-
in-device classification falls back to heuristic guessing.
