mesa-demos: fix build errors1.4_M6.rc1

When commit 6d17c9b ('emgd-driver-bin: add pkgconfig files') was added
for libva, it exposed some missing EMGD functionality, which it turns
out has been fixed by patches submitted or accepted upstream (see the
individual patches for details).

This adds those patches to get around the build problems when building
with EMGD 1.16.

Fixes [YOCTO #3469] for meta-intel (EMGD).

+Subject: [PATCH 2/2] mesa-demos: Query display for EGL_MESA_screen_surface
+ extension before using it
+
+This code makes heavy use of the EGL_MESA_screen_surface extension so 
+check the display to determine if it's supported by the underlying EGL 
+implementation. If it doesn't then bail.
