vo_opengl: change default FBO format

Reduces (but likely does not remove) the danger of rounding intermediate
values down to 8 bit. This is important for cscale, or any other

Note that some cheaper LCDs do dithering that gravely interferes with
``opengl``'s dithering. Disabling dithering with ``dither-depth=no`` helps.
