It turns out we do need to create the machine-id for the same reason
as on 8. This was being hidden by the bootloader choosing the root
disk label from the host (see the dependent change).
Change I3b518802d681b888916a5cc6a3dcf7e1b537da1e has modified the
testing to use a different root-disk label, which should help catch
this in the fututure.

Somewhere between the upstream container
rockylinux/rockylinux:8.6.20220515 and the latest release, systemd
started to be pre-installed in the container.
With <= 20220515 installing the kernel-core package would end up
pulling in systemd. As part of the systemd package installation, the
/etc/machine-id file is created and populated.
The kernel package post-install steps install the kernel with
/bin/kernel-install; this is responsible for copying the kernel
binaries into /boot. It does this based on the machine-id, and it
seems its failure case with a blank machine-id is to simply skip
copying the kernels into /boot. To compound this problem, it seems
our bootloader installation doesn't notice that we don't have a kernel
installed, so we end up building an unbootable image.
Testing is/was showing us this; but as rocky is non-voting and this
occured at a random time (rather than in response to a dib change) I
think it slipped by us.
To work around this, create the machine-id early in the container. We
already have paths that remove the machine-id from final images.

OpenDev relies on the epel role to configure the epel repository for our
image builds. Specifically we need epel to pull in haveged. Update the
epel role to recognize rocky and configure it properly.

Introduce new container image for Rocky Linux, a downstream clone of Red
Hat Enterprise Linux.
Keep non-voting in Check for a while before adding to any gate checks
