Closes#11073
In the provided link, SWF params give up to 720P, and VideoConfig
gives 1080P for both best and bestvideo. I guess all Facebook videos
supports HTML5 now, so I remove the old detection for SWF params
youtube-dl expects the format items to be returned as a list,
but when there's only one item Facebook returns a dict instead,
this wraps the dict in a list if necessary
