[PATCHv2] perf hists: change print format from lu to PRIu64

From: Tom Huynh
Date: Tue Dec 02 2014 - 15:13:18 EST

nr_events 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.

change since v1: replace %llu with PRIu64
