perf hists browser: Fix dump to show correct callchain style
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 rename the existing
function which prints graph-style callchain.
