[PATCH 1/4] perf report: Make dso__calc_col_width agree with hist_entry__dso_snprintf

[Arnaldo Carvalho de Melo <acme@infradead.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

The first was always using the ->long_name, while the later used
->short_name if verbose was not set, resulting in the dso column to be
much wider than needed most of the time.
