powerpc/boot: Add version to install filenames

Browse Source 
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.
