net/dns, ipn/ipnlocal: fix regressions from change moving away from deephash

Browse Source

I got sidetracked apparently and never finished writing this Clone
code in 316afe7d02 (#17448). (It really should use views instead.)

And then I missed one of the users of "routerChanged" that was broken up
into "routerChanged" vs "dnsChanged".

This broke integration tests elsewhere.

Fixes #17506
