screenshot: let VOs pass colorspace information via mp_image

This removes the hack that screenshot_save() got the colorspace
information from the decoder. Instead, require the VOs to set the
colorspace information on the mp_images used to pass around the
screenshot data. This is more correct, as the image may have been
converted/modified in the video filter chain, although there's
nothing yet in the video filter chain which does this correctly.
