Nick Child 269d79fb30 powerpc/boot: Add version to install filenames
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.

To extract the kernel vmlinux, System.map, .config or initrd from the zImage binary:

objcopy -j .kernel:vmlinux -O binary zImage vmlinux.gz
objcopy -j .kernel:System.map -O binary zImage System.map.gz
objcopy -j .kernel:.config -O binary zImage config.gz
objcopy -j .kernel:initrd -O binary zImage.initrd initrd.gz
