Subject: perf hists: Update the column width for the "srcline" sort key

From: Arnaldo Carvalho de Melo <[email protected]>

commit e8e6d37e73e6b950c891c780745460b87f4755b6 upstream.

When we introduce a new sort key, we need to update the hists__calc_col_len() function accordingly, otherwise the width will be limited to strlen(header).

We can't update it when obtaining a line value for a column (for instance, in sort__srcline_cmp()), because we reset it all when doing a resort (see hists__output_recalc_col_len()), so we need to, from what is in the hist_entry fields, set each of the column widths.
