perf tools: Check perf.data owner

Browse source

Add an owner check to opening perf.data files and a switch to
silence it.

Because perf-report/perf-annotate are binary parsers reading
another users' perf.data file could be a security risk if the
file were explicitly engineered to trigger bugs in the parser
(we hope of course there are non such bugs, but you never
know).
