Rather than replacing the versionless vmlinux and System.map files, copy to files with the version info appended. Additionally, since executing the script is a last resort option, inform the user about the missing `installkernel` command and the location of the installation. This work is adapted from `arch/s390/boot/install.sh`, and also matches the behaviour of arm, arm64 and riscv.
