Namhyung Kim 56772ad475 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.
