vo_opengl: restrict ES2 FBO formats 

Only a few very low bit depth internal formats can be rendered to in
pure ES2 (GL_RGB565 is the "best" one).

Seems like the only potentially reasonable renderable formats in ES2
could be provided via GL_OES_rgb8_rgba8, or half-floats, so don't
bother with this at all.
