The su domain is always permissive, and will always be permissive.
It never makes sense to show su related denials, as they just cause
a false sense of alarm.
Suppress service_manager related denials. For example:
SELinux : avc: denied { find } for service=SurfaceFlinger scontext=u:r:su:s0 tcontext=u:object_r:surfaceflinger_service:s0 tclass=service_manager
SELinux : avc: denied { find } for service=activity scontext=u:r:su:s0 tcontext=u:object_r:system_server_service:s0 tclass=service_manager
While I'm here, suppress other recent additionsl to security_classes as
well (keystore_key, debuggerd, drmservice)
