auc: add new package
The Attended sysUpgrade CLI is a full-featured client for the attended-sysupgrade service which works directly on the target device. It requires libustream-ssl as well as at least the CA certificate needed to contact the sysupgrade server. It has only been tested briefly and is by no means ready for production!
