package/kyua: fix unmet dependencies

lutok is a lua module, so it depends on ! static libs. However, the
dependency is implicit, being done because the lua modules are sourced
globally under an if-block, and thus it is not easy to find that
dependency.

Propagate that dependency to kyua, which was missing it (because it is
not a lua module, so was missing the dependency).
