gl_hwdec_vda: refuse to work with old OpenGL versions
The way we use rectangle textures (required by VDA for no reason) works onl in OpenGL 3.0 or higher. Below that, the shader will fail to compile. We could add support for older OpenGL versions, but that would be a major pain. This normally doesn't matter; mpv itself always creates OpenGL 3.2 contexts on OSX. But it could matter if a client API user uses vo_opengl_cb, and gives it a 2.1 context (which OSX also allows you to create).
