Lorenzo Colitti 78f8585339 Wait a few seconds for IPv6 connectivity to appear.
Currently, DnsTest immediately executes a DNS lookup as soon as
it starts. If the device has just connected to a network - as it
might if the test framework has just enabled wifi - and IPv6
connectivity is not yet available, the test will fail with little
proof that the network doesn't have IPv6.

Fix this by waiting for IPv6 connectivity and by adding the
active LinkProperties to the failure message.

Bug: 109670546
Test: DnsTest passes on dual-stack network
Test: DnsTest fails on IPv4-only network
