perf hists: Remove needless global col lenght calcs
To support multiple events we need to do these calcs per 'struct hists' instance, and it turns out we already do that at: __hists__add_entry hists__inc_nr_entries hists__calc_col_len for all the unfiltered hist_entry instances we stash in the rb tree, so trow away the dead code.
