Chiachang Wang e063585bbf Add permission for NetworkStack updatability
NetworkStack will need to use netlink_tcpdiag_socket to get tcp
info. In order to support updatability for NetworkStack as it's
a mainline module, get the information from kernel directly to
reduce the dependecy with framework.

Test: Build and test if NetworkStack can get the tcp_info without
SEPolicy exception
Bug: 136162280
