We often hit issues with our CentOS arm images being slightly stale.
When this happens we get openafs package build errors because available
headers don't match the running kernel. Address this by updating the
entire running system and rebooting onto any new kernel before we build
the openafs package. This should ensure our local install matches
upstream packages when it comes to kernel packages.
We also manually select the new kernel as the default kernel and remove
the old kernel with grubby as dnf doesn't reliably update the kernel to
boot automatically on arm64 centos 9 images. This is likely due to this
issue:

Also switch package module installs to dnf module installs since all of
our installations are occuring on CentOS 9 or newer.
