perf hists browser: Show folded sign properly on --hierarchy

When horizontal scrolling is used in hierarchy mode, the folded signed
disappears at the right most column.

Committer note:

To test it, run 'perf top --hierarchy, see the '+' symbol at the first
column, then press the right arrow key, the '+' symbol will disappear,
this patch fixes that.
