perf ui/stdio: Fix invalid percentage value of cumulated hist entries
On stdio, there's a problem that it shows invalid values for callchains in cumulated hist entries. It's because it only cares about the self period. But with --children behavior, we always add callchain info to the cumulated entries so it should use the value in that case.
