Drop reference to dib-utils

The dib-utils repository was retired when TripleO was retired. We
decided to vendor the dib-run-parts script in os-refresh-config so
we no longer need the separate tiny package for the dib-run-parts
script.

Depends-on: https://review.opendev.org/c/openstack/os-refresh-config/+/910574
