nixpkgs/nixos/tests/ec2.nix
Andrew Childs e4fa8192da nixos/tests/ec2: return to passing state
Updates required:

- Use vpc image format (new default, supported by Amazon)
- Pass full image filename to makeEc2Test
- Increase memory allocation for nixos-rebuild
- Set a networking.hostName for services.httpd
- Add appropriate escaping in literal userdata

While I'm here, try to make it fail fast.
