Rename tripleo-ci build-images to oooci-build-images for clash

The build-images role was added in [1] but it clashes with the
role in tripleo-quickstart-extras. This renames tripleo-ci
build-images to oooci-build-images. Also fix up the zuul layout
so the jobs run on changes to the new files. Tracked by tripleo-ci
squad in [2].
