Append two line breaks after each cue instead of just one

>From the spec[1]:

> A WebVTT file body consists of the following components, in the following order:
>
>  * [...]  
>  * Zero or more WebVTT cues and WebVTT comments separated from each other by two or more WebVTT line terminators.

You can see that we currently generate invalid WebVTT files by running this:

    gst-launch-1.0 souphttpsrc
location=http://durian.blender.org/wp-content/content/subtitles/sintel_en.srt !
subparse ! webvttenc ! filesink location=test.vtt
