screenshot: minor simplification, prefer VF over VO

Remove screenshot_force and associated logic. Always try to use the
screenshot video filter before trying taking screenshots with the VO,
which means that --vf=screenshot now takes the role of --vf=screenshot_force.
(To make this clear, not adding a video filter is still the recommended
way to take screenshots; we just change how VF screenshots are forced.)

Preferring VO over VF and having --vf=screenshot_force used to make
sense when not all VOs supported screenshots, and some VOs had somewhat
broken screenshots (like vo_xv taking screenshots with OSD in it). But
all these issues are fixed now, so just get rid of the cruft.
