fix: rework lib/bin.js inclusion in ipjx compile chain

* was included as an import in test/node-test-bin.js just to get it in the
  compile chain
* mocha now doing ESM (I think) is loading node-test-bin.js as ESM and it's
  executing bin.js as it's loaded -- this didn't happen prior to mocha@10
* only seeing this in CI for Windows, could be to do with the way mocha is
  loaded for now
* moving the import to test/noop-bin-test.js which isn't run as part of the
  test suite, but will be picked up by `ipjs --tests`
