gen-grub-cfg: Support different kernel file names 

Different architectures and/or configurations can use a different name
for the Linux kernel image file.  The `gen-grub-cfg.sh` shell script
needs to be able to identify the correct file name in the GRUB
configuration fragment it embeds in the root filesystem image.
