Fix anti-aliasing on macOS

Blitting to the resolve FBO in OSG::RenderStage was causing a GL_INVALID_FRAMEBUFFER_OPERATION due to a mismatch in attached colorbuffers between the FBOs bound in read and draw slots. This was because the normal attachment was invariantly attached to FBO_Interrupt, but not to other FBOs.
