[PATCH] perf hist browser: change print format from lu to llu to fit u64 type

[Tom Huynh]

nr_events in tools/perf/ui/browsers/hists.c is of type u64, thus it should
be printed as %llu instead of %lu. 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.
