Update CoreDNS version and Corefile in kubeadm

**What this PR does / why we need it**:
We bumped CoreDNS version to 1.0.0 (#56802) and added CoreDNS as an optional addon in kube-up (#55728), but something wrt log was missed.  The log option of CoreDNS was changed since 1.0.0. We should update the Corefile to reflect the change.
