perf hists browser: Fix hierarchy mode header

The commit ef9ff601 ("perf ui browser: Move the extra title
lines from the hists browser") introduced ui_browser__gotorc_title() to
help moving non-title lines easily.  But it missed to update the title
for the hierarchy mode so it won't print the header line on TUI at all.

  $ perf report --hierarchy
