OpenGL: Fix OBS/Overlays again by binding FB before present (#4668)
This seems to have been removed by the Post-Processing PR, but it is required for the display in OBS to be the right way up and properly scaled.

I've tested this with AA and FSR on MK8D and it seems to behave properly. Testing is welcome.
