perf hists browser: Cleanup hist_browser__fprintf_hierarchy_entry()

The hist_browser__fprintf_hierarchy_entry() if to dump current output
into a file so it needs to be sync-ed with the corresponding function
hist_browser__show_hierarchy_entry().  So use hists->nr_hpp_node to
indent width and use first fmt_node to print overhead columns instead of
checking whether it's a sort entry (or dynamic entry).
