ref(dnsupdate): move under tools

Integrate properly the tool `dnsupdate` with flake.nix, by adding a
default.nix inside its directory.

Having all the tools under a directory named `tools` is easier to reason
about. I don't need a go.mod at the top level directory either, each
tool will have its own.
