Remove dependency to old cmdlib and clap2

Summary:
We're removing all usage of old clap and old cmdlib in this quarter's hack-a-week: https://docs.google.com/document/d/17pccU80ngYcggsbGamiuDjXy8WN63kB_UQff0kayz2E/edit?tab=t.0#heading=h.9523p9s08vwn

This removes the usage in slow bookmark mover.

It's following suggestion from markbt in D73503035 to reuse an existing helper.
