resolved: support IPv6 DNS servers on the local link
Make sure we can parse DNS server addresses that use the "zone id" syntax for local link addresses, i.e. "fe80::c256:27ff:febb:12f%wlp3s0", when reading /etc/resolv.conf. Also make sure we spit this out correctly again when writing /etc/resolv.conf and via the bus. Fixes: #3359
