shim-ia32
grub2-efi-ia32-cdboot
s390utils-hmcdrvfs
xorg-x11-drivers
xorg-x11-server-Xorg
xorg-x11-server-Xorg was already being pulled in as a dependency, but
I've added it back anyway, just to be sure.
dracut-fips is no longer a subpackage so it can be dropped.
docker-anaconda-addon isn't being supported for RHEL8 so drop it as
well.
The resulting image is 6M larger, and the package count goes from 738 to
756 with most of them being x11 drv packages.
