Set rootfs size based on real size of rootfs image
ROOTFS_SIZE is recomputed for each image type based on total size of rootfs directory. If rootfs directory gets smaller between creation of rootfs image and SD image, it fill result in corrupted SD image. It should not happen in theory, but it happens occasionally for a reason I could not identify.
