Incompatibilty with webpack 5 because of missing polyfills

Webpack 5 doesn't include polyfills for node.js

node-ip code uses os-browserify, and since it's brought as a dependency bundling fails with:

```
ERROR in ./node_modules/ip/lib/ip.js 3:11-24
Module not found: Error: Can't resolve 'os' in '/home/kkoukiou/repos/cockpit-machines/node_modules/ip/lib'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "os": require.resolve("os-browserify/browser") }'
- install 'os-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "os": false }

webpack compiled with 1 error
```

The workaround is fine, but would be nice that this would be solved on this module directly.

Start by reproducing the webpack 5 bundling failure and inspect the dependency path through node-ip into node_modules/ip/lib/ip.js, especially its use of os-browserify. Compare the module's behavior with and without the consumer-side fallback; done means webpack 5 can bundle the module without requiring that workaround.
