Make "koch docs" copy the dochack.js to the right location too

- Fixes https://github.com/nim-lang/Nim/issues/9104.
- Fixes https://github.com/nim-lang/Nim/issues/9095.

Expect dochack.js to be fetched from the doc/html/ dir instead of from
doc/.

Also remove an unused and unexported proc pathPart.
