Users in the stapdev group and root can load their script module regardless of
whether it has an authorized signature, as long as it is not found as
MODULE_ALTERED.  The same should be true for loading uprobes.ko.  (We might even
permit this for stapusr, since it's loading from the installed runtime path...)

A missing or unauthorized uprobes.ko cert should only be fatal for non-root,
non-stapdev users -- i.e. unprivileged users only.
