Fix generate CRD script by using copy

Using a symlink to point inside the staging directories seems to confuse
newer versions of sigs.k8s.io/controller-tools.

Specifically, the set up of a temporary directory for controller-gen
uses a symlink into staging/api, which confuses _something_ in golang
to use ${ROOT}/staging/api/go.mod rather than ${ROOT}/go.mod, causing
it to return errors that indicate go.mod inconsistencies with
vendor/modules.txt. This would normally be fixable via the `go mod`
commands, but looking at the wrong go.mod is not a normal situation.
