[misc] Remove aur support and start service on ostree (#4461)

* Remove aur support and start service on ostree

The aur installation was adding many packages and installing more than just the client. For now is best to remove it and rely on binary install

Some users complained about ostree installation not starting the client, we add two explicit commands to it

* use  ${SUDO}

* fix if closure
