build: use translation tools from pkg/lib

Use the html2po and manifest2po tools that we already check out from
cockpit repo pkg/lib.

These tools switched to a new argument parser library (`argparse`) in
cockpit-project/cockpit#16271, so add it to our package.json and drop
`stdio`.

Drop our old copies.

I checked the result of building `po/starter-kit.pot` before and after
the change, and aside from the timestamp, it's identical.

Cherry-picked from cockpit-podman commit bf53f801b17ba6.
