NixOS/amazonImageZfs: init
Introduce an AWS EC2 AMI which supports aarch64 and x86_64 with a ZFS root. This uses `make-zfs-image` which implies two EBS volumes are needed inside EC2, one for boot, one for root. It should not matter which is identified `xvda` and which is `xvdb`, though I have always uploaded `boot` as `xvda`.
