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