Fix use of API_GROUP_VERSIONS running codegen

[mdbooth]

make target which use codegen are ignoring the API_GROUP_VERSIONS
environment variable. e.g.:

$ make verify-codegen-crds API_GROUP_VERSIONS="operator.openshift.io/v1alpha1"

will run against all group/versions.

tools/Makefile contains a 'run-codegen' target which does reference
API_GROUP_VERSIONS, but nothing seems to call this. Instead they call
hack/update-codegen.sh, which does not use it.

This change updates hack/update-codegen.sh to add the same
--api-group-versions argument as 'run-codegen'.

curious why the verify check is failing - does it fail locally for you as well?
