udp6 face creation not working

[yoursunny]

YaNFD version: a4132a8c28c87477e401d4fef74a9a3db979a7c1 nfdc version: 0.7.1-23-g6a699be8

1. Bring up a network interface and assign an IPv6 ULA address:

   sudo ip link set enp94s0 up
   sudo ip addr replace fd54:450f:f5ac:807a::2/64 dev enp94s0

2. Start YaNFD.

3. Try to create a face:

   nfdc face create udp6://[fd54:450f:f5ac:807a::1]:6363

Expected: face creation succeeds. Actual:

• nfdc returns Error 406 when creating face: Unsupported scheme udp6
• YaNFD log contains WARN[3207] [FaceMgmt] Unable to create unicast UDP face with URI udp6://[fd54:450f:f5ac:807a::1]:6363: Unsupported scheme udp6://[fd54:450f:f5ac:807a::1]:6363

This is fixed in db48f3f. This was caused by missing square brackets around IPv6 addresses.
