Usage metrics are not computed correctly when running in ipset mode

[blotus]

When running in ipset mode, the iptables counter are not reset when the bouncer stop/starts, which lead to some weird values shown in crowdsec.

We should remember the initial value of the counter, and subtract it to every subsequent metrics read to simulate the counters being 0.
