Tweak definition of a permanent IPv6 address on Linux.
The linux kernel treats all addresses with a limited lifetime as being
non permanent, but when taking over the prefix livetimes from
upstream assigned prefixes through DHCP, addresses will always have a limited
lifetime.
Still reject temporary addresses, as they indicate autoconfigured
interfaces.
