vo_opengl: don't enable PBOs with opengl-hq
The speed advantages are marginal (at least with the way it's currently used), and it might actually be slower on some drivers, like Mesa.

This is equivalent to::

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