Add kustomize to go tools (#531)

* Add kustomize to go tools

such that we all (developers and pipelines) use the same kustomize
version.

Executed
go get sigs.k8s.io/kustomize/kustomize/[email protected]

Note that v3.9.0 suffers the bug in kubernetes-sigs/kustomize#3340

Previously our pipelines used KustomizeVersion:v2.0.4-kubebuilder-special-edition.

* Remove kustomize installation from GitHub actions

since make install-tools will install kustomize
