gallium/vl: add prime support
This fixes the dri2 opening to check if DRI_PRIME is set,
and picks the correct drm device path to open, this along
with a change to libvdpau allows vdpauinfo to work at least,
Martin Peres tested with nouveau, and there seems to be a
further issue with final displaying, it only works sometimes,
but this patch is at least necessary to help debug further.
