renovate: clean up configuration

The only direct dependency in go.mod is github.com/cilium/cilium which
is updated manually before release (see
#2951).

The Go version in go.mod is already excluded from being updated by
renovate and because there are no other modules to update anymore we can
omit go.mod from being updated by renovate altogether.

Also remove some leftover configuration that no longer applies as a
result of the merge of cilium-cli into github.com/cilium/cilium.
