Marco Elver b068fc04de perf: Refactor permissions check into perf_check_permission()

Refactor the permission check in perf_event_open() into a helper
perf_check_permission(). This makes the permission check logic more
readable (because we no longer have a negated disjunction). Add a
comment mentioning the ptrace check also checks the uid.

No functional change intended.
