Use image name in DIB image IDs
Use image name in DIB image IDs

DIB image IDs used to be unique across all images. This is no longer
the case as each image uses sequence numbers within each image build.
DIB files on disk are named with <image-name>-<seq> format for the
base name. Change the dib-image-list output for the ID field to be
the combined image name/ID since that uniquely identfies DIB builds.
