Subject: [PATCH 5/5] perf tools: Fix column width setting on 'trace' sort key

It missed to update column length of the 'trace' sort key in the
hists__calc_col_len() so it might truncate the output.  It calculated
the column length in the ->cmp() callback originally but it doesn't
guarantee it's called always.
