vm: Remove obsolete procedures.
* gnu/build/vm.scm (install-efi, make-iso9660-image): Remove those procedures that are now implemented in (gnu build image) module, (initialize-hard-disk): remove efi support. * gnu/system/vm.scm (iso9660-image): Remove it, (qemu-image): adapt it to remove ISO9660 support.
