measurement: Keep average of high-accurate ToA value in lchan

At the end of a measurement processing window, we currently compute
the ToA / timing offset at 1/256th symbol accuracy, but we only print
it to the log.  Let's store the value in the lchan to make it usable
by other code in follow-up patches.
