build profiles - feature complete

* setup-ami.sh
+ fix partitioning
+ proper path to grub-install
+ don't forget to umount /boot/efi during cleanup
* version/edge - newer kernel trusts CPU for entropy, don't need haveged anmore
* test.conf
+ reduce ami_regions to just us-west-2
+ entropy stuff moved to version/edge
+ adds edge-aarch64 build (though AMI's arch isn't set properly - https://github.com/hashicorp/packer/issues/7358
* alpine-amis.conf - prepend 'r' to revision number
