perf hist browser: Fix hierarchy column counts
The perf report/top on TUI supports horizontal scrolling using LEFT and RIGHT keys. But it calculate the number of columns incorrectly when hierarchy mode is enabled so that keep pressing RIGHT key can make the output disappeared. In the hierarchy mode, all sort keys are collapsed into a single column, so it needs to be applied when calculating column numbers.
