vm_image_util: Use larger rootfs for AWS and Akamai images

The default rootfs size for the .bin raw iamge is a bit smaller now
because we still want to be able to flash to 8 GB storage. However, the
VM images still have the 6 GB rootfs as before. Some cloud images
weren't using the larger VM rootfs size though but the raw image rootfs
size.
Specify that AWS and Akamai images should use the larger VM rootfs size.
