armvirt: fix overlay support by updating to f2fs/ext4 based overlays
Current snapshot images doesn't provide images with usable overlay filesystems: mount_root: no usable overlay filesystem found, using tmpfs overlay So this patch fixes this by updating support to current f2fs/ext4 based overlays and providing squashfs with proper rootfs TARGET_ROOTFS_PARTSIZE size. While at it, I've also added support for optional gzipping of the images, and renamed the output rootfs image filenames to match the more common naming pattern $(IMG_PREFIX)-rootfs-$(FS-TYPE).img.
