hack: use go 1.17 for verifying codegen

The hack/verify-codegen.sh script was using an image that included
go 1.16. However, the updated k8s.io/json module calls the
`(reflect.StructField) IsExported` function, which is new in go 1.17.
Consequently, the script needs to be updated to use an image that
include go 1.17 rather than 1.16.
