perf stdio: Add use_callchain parameter to hists__fprintf

It will be convenient in following patches to display hists entries without callchains even if they are defined.

PATCH 9/11 perf tools: Replace perf_evsel arg perf_hpp_fmt's header callback

In reply to Jiri Olsa

Replacing perf_evsel arg perf_hpp_fmt's header
callback with hists object.

No of actual callbacks actually use evsel object,
also this will be helpful in future for non evsel
related hist browsers.

perf hists: Replace perf_evsel arg perf_hpp_fmt's width callback

Replacing perf_evsel arg perf_hpp_fmt's width callback with hists object.

This will be helpful in future for non evsel related hist browsers.
