vm: Add support for registering closures to make-iso9660-image.
This mimics the functionality in the root-partition-initializer used in creating the QEMU image. This helps when trying to run guix system init from the generated ISO image. * gnu/build/vm.scm (make-iso9660-image): Add support for registering closures.
