Update with latest CoreDNS to fix build issues.

[davidmccormick]

The tests for coredns/ci are failing coredns/ci#157 because the metadata_edns0 plugin is failing to build:

github.com/coredns/metadata_edns0
# github.com/coredns/metadata_edns0
link: golang.org/x/net/internal/socket: invalid reference to syscall.recvmsg
make: *** [Makefile:32: build] Error 1
[+] Building 0.3s (13/13) FINISHED                               docker:default
=> [internal] load build definition from Dockerfile                       0.0s

The PR updates go.mod/sum with the latest CoreDNS and runs go mod tidy in order to attempt to fix the build issues.

Update CoreDNS to v1.11.3
Update miekg/dns to v1.1.58
