[Beignet] Sample program crash with beignet 0.3 on IVB

[Zhigang Gong]

The root cause of this is that the cl_khr_gl_sharing extension depends
on a specific mesa version:

92e6260c1960f78692417433206c38170ec1a625

You can find your mesa source code tree. It should be in ${HOME}/mesa.
Or you can check the CMakeCache.txt in your build directory to find
the following statement:

//Set to 1 if mesa source code is found, 0 otherwise
MESA_SOURCE_FOUND:STRING=1

//The mesa source directory which is needed for cl_khr_gl_sharing.
MESA_SOURCE_PREFIX:PATH=dir-to-your-mesa-source-code

You can enter the above mesa source code directory and checkout the above specific
version and rebuild and install mesa, then build beignet again.

If you don't want to use cl_khr_gl_sharing, you can just simply rename that
mesa source code directory to another name or use ccmake to set MESA_SOURCE_FOUND
to zero, then configure and regenerate the build files.
 MESA_SOURCE_FOUND                0
