Test correctness of NRD prefix registration and FIB updates (without ForwardingFlags processing).

1. Modify $HOME/.ndn/client.conf to choose "protocol=nrd-0.1".
2. Start NFD.
3. Run nfd-status to obtain FIB.
4. Start ndn-traffic-server; configuration has one or more non-overlapping prefixes.
5. Run nfd-status to obtain FIB. Compare new FIB to the FIB from step 3, and determine whether FIB entry is inserted
6. Stop ndn-traffic-server.
7. Run nfd-status to obtain FIB. Compare new FIB to the FIB from step 5, and determine whether FIB entry is deleted
