I'm not entirely sure the check is needed anyway. This is a trusted
application sending audit messages. Why shouldn't it be permitted to log
auditable events which were triggered by someone _else_? 

If we want to audit the actions of the userspace logging dæmon itself
and see what it sends, then we can quite happily do so within the audit
framework. That's a _different_ issue, surely?
