[yocto] [PATCH 2/3] cdv-pvr-driver: add xorg-abi-video- dependency

[Ross Burton]

xserver changes the driver ABI at will, and refuses to load drivers with the
wrong ABI version. So that we know about this error at image build time instead
of when xserver fails to start, RDEPEND on the ABI version we expect.

This dependency is added programmatically so that bitbake doesn't look for a
provider of xorg-abi-video-8 at parse time, which it won't find.
