dlna: also look at "Subs" subdirectory

Browse Source 
Apparently it seems pretty common for subtitles to be put in a
subdirectory called "Subs", rather than in the same directory as the
media file itself.

This covers that usecase, by checking the returned listing for a
directory called "Subs" to exist.

If it does, its child nodes are added to the list before they're being
passed to mediaWithResources, allowing these subtitles to be discovered
automatically.
