screenshot: clarify software screenshot logic

Browse Source 
We should always be trying hardware screenshots (VOCTRL_SCREENSHOT and
VOCTRL_SCREENSHOT_WIN) before software ones. Rearrange all the logic
here to hopefully make this clearer. The mode is passed to add_osd
(renamed since it will also be used to add the osd) which will be used
more in the next commit.
