IVI: Prefer Mesa OpenGL(/ES) libs in all configurations

IVI: Prefer Mesa OpenGL(/ES) libs in all configurations

Making one version of these libraries preffered in any configuration
makes it possible to keep multiple versions in the same repository.
If all of the versions are binary compatible, the correct version
for the platform can be selected by explicitly specifying it in the
kickstart file during image creation.
