Subject: radvd: T6118: add nat64prefix support RFC8781

Add support for pref64 option, as defined in RFC8781. The prefix valid lifetime
must not be smaller than the "interface interval max" definition which defaults
to 600.

  set service router-advert interface eth1 nat64prefix 64:ff9b::/96

(cherry picked from commit f1ead5c6a16aba00699b8a5b9c18ef6cffe8cc4d)
