conf: Fix initialisation of IPv6 unicast and link-local addresses
In commit 675174d4ba25 ("conf, tap: Split netlink and pasta functions, allow interface configuration"), I broke the initial setting of the observed IPv6 addresses in two ways: - the size copied from the configured addresses corresponds to an IPv4 address, not to an IPv6 address - the observed link-local address is initialised to the configured unicast address, not the link-local one If we haven't seen the guest using some type of addresses yet, we should default to the configured values, hence these initial settings: fix both. This resulted in UDP flows to the guest from a unique local address on the network not working before the guest shows passt a valid address itself, as reported by Alona.
