ui/sdl: Fix handling of caps lock and num lock keys
Starting with SDL version 1.2.14, caps lock and num lock keys will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in the environment. The new code sets the environment unconditionally (it won't harm old versions which do not know it). The workaround for SDL_KEYUP is only compiled with old SDL versions. A similar patch without handling of old SDL versions was already published by Benjamin Drung for Ubuntu.
