Patch to resolve the problem

Hi,

I have detected that when I use curlhttpsink after a qtmux with faststart the
sink doesn't work fine. 

The sink receives a first empty buffer and it doesn't receive more buffers
until the end of the video. However, the sink starts to send empty http
requests with the first buffer and the sending never works fine.

I attach a patch that resolves the problem this avoiding empty buffers.

You can check the bug with this simple pipeline:
gst-launch-1.5 videotestsrc num-buffers=1000! x264enc ! qtmux faststart=TRUE !
curlhttpsink location=http://127.0.0.1:8080/

If you put a http-server you will be able to detect empty packages since the
begining of the execution and the execution never ends. With my patch, this
doesn't occur.

Thank you.
David.
