Report a minute's bandwidth as bytes per second

setconnectioninfo sent the bytes of the whole last minute where the
server expects the minute's average rate, so others saw our bandwidth
60 times too high. PacketStatistics gains the per-second averages, and
the packets-last-minute count looked at the last second only.
