talosctl non-unix builds broken.

Explicitly enable access to host DNS from pod/service IPs.
Also fix the Kubernetes health checks to assert number of ready pods to
match expectation, otherwise the check might skip a pod (e.g.
`kube-proxy` one) which is not ready, allowing the test to proceed too
early.
Update DNS test to print more logs on error.

- By default, github.com/miekg/dns uses `dns.MinMsgSize` for UDP messages, which is 512 bytes. This is too small for some
DNS request/responses, and can cause truncation and errors. This change sets the buffer size to `dns.DefaultMsgSize`
4096 bytes, which is the maximum size of a dns packet payload per RFC 6891.
- We also retry the request if the response is truncated or previous connection was closed.
- And finally we properly handle the case where the response is larger than the client buffer size,
and we return a truncated correct response.

Run a health check before the test, as the test depends on CoreDNS being
healthy, and previous tests might disturb the cluster.
Also refactor by using watch instead of retries, make pods terminate
fast.

More specifically, pick up `/etc/resolv.conf` contents by default when
in container mode, and use that as a base resolver for the host DNS.
