qt4-graphics-system: add

Allow setting default runtime graphics system engine for Qt4
applications per machine.

Depending on the GPU and Xorg driver, this can boost and impact
significantly the drawing performance. The default setting is to
'raster' as this offer best performance for most machines GPUs.
