Add report.children config option for setting default value of
callchain accumulation. It affects the report output only if
perf.data contains callchain info.
A user can write .perfconfig file like below to enable accumulation
by default:
$ cat ~/.perfconfig
[report]
children = true
And it can be disabled through command line:
$ perf report --no-children
