BUG/MEDIUM: peers: fix incorrect age in frequency counters

The frequency counters's window start is sent as "now - freq.date",
which is a positive age compared to the current date. But on receipt,
this age was added to the current date instead of subtracted. So
since the date was always in the future, they were always expired if
the activity changed side in less than the counter's measuring period
(eg: 10s).

This bug was reported by Christian Ruppert who also provided an easy
reproducer.

It needs to be backported to 1.6.
