perf ui/stdio: Always reset output width for hierarchy
When the --hierarchy option is used, each entry has its own hpp_list to
show the result. But it is not updating the width of each column for
perf-top. The perf-report command has no problem since it resets it
during header display.
$ sudo perf top --hierarchy --stdio
PerfTop: 160 irqs/sec kernel:38.8% exact: 100.0%
[4000Hz cycles:pp], (all, 12 CPUs)
----------------------------------------------------------------------
52.32% perf
24.74% [.] __symbols__insert
5.62% [.] rb_next
5.14% [.] dso__load_sym
Move the code into hists__fprintf() so that it can be called always.
Also it'd be better to put similar code together.
