[Build] Detach :liraries:tools:dukat module from root gradle project

This is needed to prevent leaking dependency on `dukat:0.5.8-rc.4` into
  dependency of Kotlin project after import to IDE. This jar contains
  unshaded classes of some outdated compiler version and it confuses
  IDEA tooling (like debugger), so it shows those classes instead of
  real sources from project
