Update third_party/libva to version 1.7.1

$ git clone https://github.com/01org/libva.git
$ cd tmp/libva
$ git checkout libva-1.7.1
$ rm -rf ~/chromium/src/third_party/libva/va
$ find va -name \*.h -exec cp --parents \{\} ~/chromium/src/third_party/libva \;
$ sh build/gen_version.sh . va/va_version.h.in > ~/chromium/src/third_party/libva/va/va_version.h

Also Remove:
- remove va/egl/va_egl.h due to the lack of license header
- remove struct _VAEncMacroblockParameterBufferH264 from va/va_enc_h264.h,
  which contained an empty union, causing compile errors

BUG=None
TEST=build and test VDA and VEA on an Intel device.
