Revert "cki-tools image: add kernel-ark scheduled job package dependencies"

This reverts commit d3f983ad.

Instead of using cki-tools image, kernel-ark will use builder-rawhide image after containers!559 (merged). So the additions to cki-tools here are no longer necessary.

Part of: kernel-ark#159 (closed)
