Remove fixed storage-driver
    
    Instead of configuring the docker daemon to use a fixed storage-driver remove the setting and let it decide which one to use.

    

    Trying to use the moby-engine package on a Fedora33 I was getting the error described here https://github.com/kubernetes-sigs/kind/issues/1988 because of the default btrfs filesystem, removing the storage-driver setting from docker's sysconfig fixes it.
