generate kube: handle entrypoint

The spec of a Kube Container has a `Command` and `Args`.  While both are
slices, the `Command` is the counterpart of the entrypoint of a libpod
container.  Kube is also happily accepting the arguments to as following
items in the slice but it's cleaner to move those to `Args`.

Fixes: #9211
