classes/image_types: Add vfat image type
Adds support for creating FAT formatted file system images (useful for
boot partitions on some SoCs).
Note that FAT partitions are limited in what they can represent (no
symlinks or device files), so they can't really be used for general
purpose root file systems. As such, they are skipped when testing for
that purpose.
