remove replace directives

go.mod contains many replace entries that all consumers must include to
import logic. These are cancerous and tend to make consumers builds
difficult or outright fail. All have been removed, except for the one
required by helm-operator. This entry, required transitively by
helm-operator, should be removed when distribution/distribution#2905 closes.
