vzmigrate: show separate pcopy2 time

In case we use ploop copy, second stage of it (after suspend)
is happening just sefore dump, so "Suspend + Dump" time now includes
time of pcopy second stage. Calculate this second stage pcopy time, show
it as Pcopy2, and subtract its value from "Suspend + Dump" time.
