Adel Gadllah 62fcd364ac dri2: Set vdpau driver name if ddx does not provide any driver name 
Currently when the ddx does not set any driver name we set DRI2 driver but
not the VDPAU driver name. The result is that VDPAU drivers will not get found
by libvdpau when the modesetting driver is being used.

Just assume that the VDPAU driver matches the DRI2 driver name, this is true
for nouveau, r300, r600 and radeonsi i.e all VDPAU drivers currently supported
by mesa.
