mesa, st/mesa: disable GL_ARB_geometry_shader4

The new GLSL compiler doesn't support geom shaders yet so disable the
GL_ARB_geometry_shader4 extension.  Undo this when geom shaders work again.

NOTE: This is a candidate for the 7.10 branch.

(cherry picked from commit bb7c2691d25b6aaea2663f85a5b6723edbf56938)
