backends/drm: only allow ARGB8888 as the cursor format

Browse source 
The raspberry pi exposes opaque formats for the cursor plane, and interprets
them as being opaque as well... Considering that we effectively don't support
anything else with the QPainter anyways, just hardcode ARGB8888 until we paint
the cursor with OpenGl.
