Use requested bitrate in iperf3 UDP analysis function

Browse Source 
Sender bitrate is not always equal to the requested bitrate (set by "-b" iperf option) in iperf3 (v3.9) UDP tests, so we have to compture bitrate performance of UDP iperf3 test as receiver over requested bitrate. Bitrate performance then express percentage of requested bitrate, which is received on the receiver side.
