    Set and export DIB_RELEASE for centos7

    The default value was set in the centos7 element, but not
    exported, which caused issues in rpm-distro. Also changed
    a test in rpm-distro to only check for DIB_RELEASE > 22
    if it's fedora.

    Closes-Bug: #1477172

After the change implemented above, I can't seem to set DIB_RELEASE outside of diskimage-builder and have it build with that image. I'm guessing I can fix that by setting DIB_CLOUD_IMAGES and BASE_IMAGE_FILE outside of diskimage-builder. Can you default DIB_RELEASE to GenericCloud but allow it to be set from outside diskimage-builder?
