Subject: [PATCH] nixos/amazon-image: (temporarily) use fixed disk size again

As a temporary workaround for #120473 while the image builder is patched
to correctly look up disk sizes, partially revert
f3aa040bcbf39935e7e9ac7a7296eac9da7623ec for EC2 disk images only.

We retain the type allowing "auto" but set the default back to the
previous value.
