perf hists: Reset width of output fields with header length
Some fields missed to set default column length so it broke align in
--stdio output. Add perf_hpp__reset_width() to set it to a sane
default value.
Note that this change will ignore -w/--column-widths option for now.
Before:
$ perf report -F cpu,comm,overhead --stdio
