tools: remove lint-js.js

lint-js.js was implemented before ESLint had a caching feature. It is
now only used in CI. Let's remove it on the following grounds:

* It results in occasional (and puzzling) yellow CI runs for
  node-test-linter because the tap file is corrupted somehow.
  Interleaved maybe? I don't know, but a simple solution is removing it
  and running ESLint directly.

* On my local laptop, it reduces the linting from about 75 seconds to
  about 55 seconds. This kind of savings is not worth the added
  complexity and the instability noted above.
