test: Select first reported IPv6 address for guest/host comparison
If we run passt nested (a guest connected via passt to a guest connected via passt to the host), the first guest (L1) typically has two IPv6 addresses on the same interface: one formed from the prefix assigned via SLAAC, and another one assigned via DHCPv6 (to match the address on the host). When we select addresses for comparison, in this case, we have multiple global unicast addresses -- again, on the same interface. Selecting the first reported one on both host and guest is not entirely correct (in theory, the order might differ), but works reasonably well. Use the trick from 5beef085978e ("test: Only select a single interface or gateway in tests") to ask jq(1) for the first address returned by the query.
