coreutils comes in two variants now, 'coreutils-single' which is a
busybox-like single binary called through symlinks and the regular
coreutils. Both satisfy the dependency for coreutils for any other
packages, but if you explicitly ask to install coreutils over
coretuils-single you get an error.
Since coreutils-single is already in the base-image, just skip
installing it on Rocky 8.
