image-live: fix check for rootfs size with hddimg images
Currently we check if the rootfs.img size is greater than 4 GB and use
mcopy to copy it over to a hddimg, a FAT32 volume.
This results in problems when IMAGE_ROOTFS_SIZE is set to be exact 4 GB
(
4294967296 bytes). mcopy uses the max offset/file size to be
4294967295
and as a result, it errors out without any warning to the user.
Change the 4 GB check to '-ge' to catch these cases. Since we allow
IMAGE_ROOTFS_SIZE to be in KBs, the maximum allowed is
4194303 KB. Also,
tweaked the error message to refer to wic too.
