pop: add versionCheckHook and explicit updateScript

This should make runtime failures easier to notice during building.
Even tho there isn't a `passthru.updateScript` defined, the package is
being automatically updated. I added an explicit `nix-update-script`
reference just to make it explicit that the package is being updated
automatically.
