    file-info: catch thumbnail files in large directory as well
    
    When building the file attribute table info for local files, use
    thumbnail paths in $XDG_CACHE_DIR/thumbnails/large in addition to
    $XDG_CACHE_DIR/thumbnails/normal.
    
    Failing to do this would cause an application that creates large
    thumbnails by default to never find any value for
    G_FILE_ATTRIBUTE_THUMBNAIL_PATH, with no
    G_FILE_ATTRIBUTE_THUMBNAILING_FAILED set, which might cause the
    application to either think thumbnailing is still in progress, or
    blindly requeue thumbnail operations in a loop.
    
    Large thumbnails are generally preferred, so we now default to the path
    of a large thumbnail (in case both are present).
