perf tools: Defaults to 'caller' callchain order only if --children is enabled

Browse Source 
The caller callchain order is useful with --children option since it can
show 'overview' style output, but other commands which don't use
--children feature like 'perf script' or even 'perf report/top' without
--children are better to keep callee order.
