    gles: Or in private features into ctx->private_feature_flags
    
    When we moved all the GL function pointers to be part of CoglContext in
    commit dae02a99a5c8c5 we made a mistake and started to OR in the private
    COGL_PRIVATE_FEATURE_TEXTURE_2D_FROM_EGL_IMAGE feature flag into the non
    private flags which would mean cogl would think the GL_OES_EGL_image
    extension wasn't supported.
