Fix JPEG RTP payloader for Logitech B990 HD Webcam that adheres to
www.quickcamteam.net/uvc-h264/USB_Video_Payload_H.264_0.87.pdf.

The Logitech B990 HD Webcam follows the specification below to expose H.264
encoded video in the MJPEG container.  As a result the GStreamer JPEG RTP
payloader fails to correctly frame the MJPEG content that is delivered to it. 
Attached is a patch that I came up with to address this problem.
