bootloader: Add 'disk-image-installer'.
* gnu/bootloader.scm (<bootloader>)[disk-image-installer]: New field, (bootloader-disk-image-installer): export it. * gnu/bootloader/grub.scm (install-grub-disk-image): New procedure ... (grub-bootloader): ... used as "disk-image-installer" here. (grub-efi-bootloader): set "disk-image-installer" to #f. * gnu/system/image.scm (root-partition?, find-root-partition): Move to "Helpers" section. (root-partition-index): New procedure. (system-disk-image): Honor disk-image-installer, and use it to install the bootloader directly on the disk-image, if supported.
