daemon: remove v1 shim configuration for containerd 
This removes the plugin section from the containerd configuration file
(`/var/run/docker/containerd/containerd.toml`) that is generated when
starting containerd as child process;

```toml
[plugins]
  [plugins.linux]
    shim = "containerd-shim"
    runtime = "runc"
    runtime_root = "/var/lib/docker/runc"
    no_shim = false
    shim_debug = true
```

This configuration doesn't appear to be used since commit:
0b14c2b67a, which switched the default runtime
to to io.containerd.runc.v2.

Note that containerd itself uses `containerd-shim` and `runc` as default
for `shim` and `runtime` v1, so omitting that configuration doesn't seem
to make a difference.

I'm slightly confused if any of the other options in this configuration were
actually used: for example, even though `runtime_root` was configured to be
`/var/lib/docker/runc`, when starting a container with that coniguration set
on docker 19.03, `/var/lib/docker/runc` doesn't appear to exist:

```console
$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES

$ ls /var/lib/docker/runc
ls: /var/lib/docker/runc: No such file or directory

$ ps auxf
