distro/rhel-8.2: update VHD images to be closer to lorax

The current one was taken from fedora and that failed both due to an
SELinux bug in RHEL8.2, but also because the list of packages was
wrong for the distro.

We don't enable WAAgent, which we probably should. And there are a few
other config tweaks to cloud-init and WAAgent that we skip too.
