st/va: hardlink driver instances to gallium_drv_video.so

Removes the need to set LIBVA_DRIVER_NAME=gallium for supported targets and is
consistent with vdpau and general gallium drivers.

Note: some versions of libva can detect the gallium name and use the
backend. Although that behaviour seems inconsistent since it only works
for some platforms/backends.
