gnu: vm: 'qemu-image' populates /dev on the target root file system.
* gnu/system/vm.scm (qemu-image): Use (guix build linux-initrd). Remove
'mknod' calls; use 'make-essential-device-nodes' to populate /dev on
the target image.
* gnu/packages/linux-initrd.scm (qemu-initrd): When /root/dev exists,
don't call 'make-essential-device-nodes'.
