different contents or permissions error

Bug Description

Hello team!
A follow up from the Matrix thread regarding the error when trying to merge the lib directory together.

The problem seems to be with the NPM plugin, when using npm-include-node:true and npm-node-version options, which writes node_modules to the /lib directory.

This requires a dummy package.json at the source/root directory.

{
  "name": "app",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "cookie-parser": "~1.4.4",
    "debug": "~2.6.9",
    "express": "~4.16.1",
    "http-errors": "~1.6.3",
    "jade": "~1.11.0",
    "morgan": "~1.9.1"
  }
}

To Reproduce

1. Create the files above (rockcraft.yaml, package.json).
2. rockcraft pack
3. error: Detailed information: Parts 'test/runtime' and 'expressjs-framework/install' list the following files, but with different contents or permissions: lib
