[PATCH] perf tools: do not complain if root is owning perf.data

[Pierre Habouzit <pierre.habouzit@intersec.com>]

This improves patch fa6963b24 so that perf.data stuff that has been dumped
as root can be read (annotate/report) by a user without the use of the
--force.

Rationale is that root has plenty of ways to screw us (usually) that do
not require twisted schemes involving specially crafting a perf.data.
