    cogl-pipeline-state: Define GL_FUNC_ADD so it'll compile for GLES1
    
    When compiling with just the GLES1 headers GL_FUNC_ADD isn't
    defined. There was already a #define for this in cogl-pipeline.c so that
    setup_blend_state could work but this function has moved to
    cogl-pipeline-state.c so the #define needs to be moved as well.
