Prepare for move zz_generated_deepcopy.go to k8s.io/api

This is in preparation to move deep copies to with the types to the types repo (see https://github.com/kubernetes/gengo/pull/47#issuecomment-296855818). The init() function is referring the `SchemeBuilder` defined in the register.go in the same packge, so we need to revert the dependency.

This PR depends on https://github.com/kubernetes/gengo/pull/49, otherwise verification will fail.
