mesa: fix MAX_GEOMETRY_IMAGE_UNIFORMS check support

MAX_GEOMETRY_IMAGE_UNIFORMS are supported if geometry shaders and either
ARB_shader_image_load_store or GLES 3.1 are supported.

v2:
 - MAX_GEOMETRY_IMAGE_UNIFORMS shouldn't be supported for GL 3.2 if
   ARB_shader_image_load_store is not supported (Ilia).
 - MAX_TESS_{CONTROL,EVALUATION}_IMAGE_UNIFORMS requires tessellation
   shader support (Anholt).

v3:
 - Use _mesa_is_gles31() function (Ilia).
