[PATCH 06/12] perf hists browser: Fix dump to show correct callchain style

[Namhyung Kim]

The commit 8c430a348699 ("perf hists browser: Support folded
callchains") missed to update hist_browser__dump() so it always shows
graph-style callchains regardless of current setting.

To fix that, factor out callchain printing code and renamethe existing
function which prints graph-style callchain.
