Switch patch images to rhel-9

Looks like the KAO/KCMO image which we do now move to rhel-9 and we are still using rhel-8 tag

 $ git show upstream/rhaos-4.15-rhel-8 77e5a08f25319a2926d567d47266dad8a8911af9
fatal: bad object 77e5a08f25319a2926d567d47266dad8a8911af9

$ git fetch upstream rhaos-4.15-rhel-9 --no-tags
$ git log --oneline  upstream/rhaos-4.15-rhel-9
