Set containerd root explicitly (#2476) (#2791)

Browse Source 
With the move to Docker 23 containerd stores its metadata no longer
undernath the Docker data directory but at its default location at
/var/lib/containerd. Previously Docker passed a containerd configuration
toml file which explicitly set the metadata root underneath Docker's
data directory.

On Home Assistant OS, the new location /var/lib/containerd is on a tmpfs
file system. For unknown reasons, it seems that if containerd's root
directory is on a tmpfs this leads to significantly more syscalls and
hence CPU load.

Change the metadata location to be on the data partition again. Since
containerd is treated separately from Docker these days, use a new
root directory under /mnt/data for containerd as well. With this, the
CPU load of containerd is back to normal.
