[PATCH v4 4/9] perf annotate browser: Show the proper header when using --show-total-period

[Taeung Song]

Currently a first column is only "Percent",
so fix it to show correct column name based on given options.
(e.g. if using --show-total-period or a 't' hotkey,
show "Event count" as a first column)

perf annotate TUI: Fix column header when toggling period/percent

We have the 't' hotkey to toggle showing either the total period or the
percentage of samples for a given line, but we forgot to toggle as well
the column header, always showing "Percent", even when showing the
period, fix it.
