perf hists browser: Add back callchain folding symbol

The commit 5395a04841fc ("perf hists: Separate overhead and baseline
columns") makes the "Overhead" column no more the first one, this
caused the test that checks if it is time to show if a histogram
entry has callchains never hits.

Fix it by checking if the 'i' variable is equal to PERF_HPP__OVERHEAD
instead of 0.
