Delete 16-bit COMBOOT supportsyslinux-5.00
16-bit COMBOOT files are no longer supported by Syslinux in 5.00 so
delete all references and change any 32-bit COMBOOT image references
to mention ELF instead.
Some of the COMBOOT stuff is still used internally so we can't nuke
core/comboot.inc yet, but that will disappear in a future release.
