[PATCH v2 1/2] perf tests kvm: Avoid leaving perf.data.guest file around

[Ian Rogers <irogers@google.com>]

Ensure the perf.data output when checking permissions is written to
/dev/null so that it isn't left in the directory the test is run.

Fixes: b58261584d2f ("perf test kvm: Add some basic perf kvm test coverage")
