system: vm: Add arm64 support.
* gnu/build/vm.scm (load-in-linux-vm): Add target-arm64? argument and use it to pass correct arguments to qemu. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass the new target-arm64? argument added above. Do not add ESP partition on all ARM targets. Do not pass grub-efi package to initialize-hard-disk on ARM targets.
