Security: Add Hook to test if the particular xattr is part of a MAC model.
The interface to request security labels from user space is the xattr interface. When requesting the security label from an NFS server it is important to make sure the requested xattr actually is a MAC label. This allows us to make sure that we get the desired semantics from the attribute instead of something else such as capabilities or a time based LSM.
