build: don't remove lib directory in prepack script

[rossiam]

• Removed command removing lib directory in prepack script.
• Added a little debug to the packaging. We might want to remove this at some point in the future but I think it would be good to leave it in for a couple releases.

Checklist

• I have read the CONTRIBUTING document
• Any required documentation has been added
• My code follows the code style of this project (npm run lint produces no warnings/errors)
