[Beignet] [PATCH V2] Fix libva examples build error

[Xiuli Pan]

From: Pan Xiuli <xiuli.pan at intel.com>

Now libva has moved from freedesktop to github and been spilt into two
projects. Change the submodule to make sure the test case can be built.

Upgrade Guide: If you have tried old freedesktop libva, you should run
git submodule deinit -f .
first to remove all of the cache of the old version libva.

V2: Add some guide to upgrade libva and fix examples Cmake file.
