Subject: [PATCH 04/18] perf hists browser: Change print format from %lu to %PRIu64

From: Tom Huynh <tom.huynh@...escale.com>

The nr_events variable in tools/perf/ui/browsers/hists.c is of type u64,
so the print format (%lu) causes 'perf report' to show 0 event count
when running with 32-bit userspace without redirection.

This patch fixes that problem by printing nr_events as PRIu64.
