movenc: use similar logic to DASH when writing bit rate to ISML

Browse Source 
This way, in case of bit rate not being set, max_bitrate will be
used instead. This enables, for example, re-using max_bitrate
information from the input or doing transcoding with a rate
control mode that is not bit rate based.
