xf86: dri2: Use va_gl as vdpau_driver for Intel i965 GPUs

Merged Hans de Goede requested to merge jwrdegoede/xserver:i965-vdpau_driver into master

The modesetting driver (which now often is used with Intel GPUs), relies on dri2_probe_driver_name() to get the dri and vdpau driver names, before this commit it would always assign the same name to the 2 names. But the vdpau driver for i965 GPUs should be va_gl (i915 does not support vdpau at all).

This commit modifies the used lookup table and dri2_probe_driver_name() to set the vdpau_driver to va_gl for i965 GPUs, it leaves the 2 names the same for all other GPUs.

Note this commit adds a FIXME comment for a memory leak in dri2_probe_driver_name(), that leak was already present and fixing it falls outside of the scope of this commit.
