[PATCH] perf timechart: Use pr_debug to report unknown header types

[Arnaldo Carvalho de Melo <acme@redhat.com>]

It was using eprintf that checked if verbose was !zero, when I converted
to pr_*() I made the mistake of changing it to pr_warning which caused
'perf timechart' output to be way too verbose.
