perf hists browser: Fix percentage update on key press
Currently 'perf top --tui' decrements percentage of all entries on any
key press. This is because it adds total period as new samples are
added to hists. As perf-top does it currently but added samples are not
passed to the display thread, the percentages are decresing
continuously.
So separate total period stat into a different variable so that it
cannot affect the output total period. This new total period stats are
used only for calcualating callchain percent limit.
