Add TV devices that have MdnsOffloadManagerService to APF exempt list 

For Panel TV devices, the vendor can implemented TV specific mDNS
offload instead of APF in U. If TV specific mDNS offload is implemented.
MdnsOffloadManagerService will exist in the system ext partition. The
APF vts will be skipped if MdnsOffloadManagerService exist.
