ytdl_hook: Support playlist entries without subtitles

Browse Source 
Fixes missing subtitle tracks if the first entry didn't have any.

Previously it just checked for the first entry in the playlist for
requested languages and if that entry happened to not have subtitles
they also wouldn't show up for the other entries.

It will skip languages if the first entry with subs has less or
different languages than the others.

Unrelated to http_dash_segments.
