Fixed bug 4347 - Keyboard LEDs don't work on linux console 

Rainer Sabelka

When using SLD2 on a Linux console with the KMS/DRM video backend and Linux evdev keyboard support, the caps lock, scroll lock, and num lock leds do not work.

The attached patch adds ioctls for setting the LED state in SDL_evdev_kbd.c
