/usr/share/security-manager/policy/privilege-group.list

In case of App, 'priv_*' group is assigned by it's cynara privilege.
But, user daemon also has related 'priv_*' groups.
Due to this group assignment policy rule for group priv_* affects application, user daemons and process who has priv_*.
To prevent this unintended situation, block rule for group 'priv_*'.
