ci-dockerfiles-sanity-check: Remove to recreate as a different job type

This job is currently a matrix job with a single configuration, which makes
its usage and maintenance a bit confusing. We can't just change the type of
existing job from matrix to normal ("freestyle") in Jenkins, so will remove
and then immediately recreate as such.
