Pass local copy of input to RtpH263ReaderTest's consume method

This change is done to keep the frame data unchanged.
RtpH263Reader changes the header data in input, so to send the same
RTP packet across multiple tests, each test copies the frame data
into a new packet and sends that to the reader.
