Kernel/LibInput: Rework Joystick handling

Joystick axis and buttons are now named to standard values, this allows
interfacing multiple different controllers (only DS3 is supported)

Add ioctl calls for userspace to set joystick player leds and rumble

Only use DS3 code paths when we detect that the attached device is
actually an DS3 controller

update test-joystick program to the new interface and add support to
control rumble and player leds
