vm: Support creating FAT partitions.

* gnu/build/vm.scm (create-ext-file-system, create-fat-file-system): New procedures.
(format-partition): Use them. Error for unknown file systems.
* gnu/system/vm.scm (qemu-image): Include DOSFSTOOLS.
* gnu/system/linux-initrd.scm (base-initrd): Always add nls_is8859-1.ko.
