Node.js v17.1.0

It appears that it's trying to find it's own package.json file using a relative path. In the repo and source tarball, `cli.{ts,js}` is `src/bin/` but in the package this is `build/src/bin` causing the relative path to be different. Copying the packages.json into the `build` directory fixes the problem but I don't know what's the correct fix....

Additional info:
* package version(s) 12.0.2
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
Just run `ncu` command.
