rib: Refactor initialization of NRD instance
This commit also makes Face used inside NRD be adaptive to nfd.conf.
More specifically, it will use the same unix socket path as specified in
face_system.unix section. If this section is not present, it will use
the same tcp port as specified in face_system.tcp section. If tcp
section is also absent, nrd will abort execution.
