ztp: Downgrade MCO to an ignition version v3.2.0

ZTP must produce MachineConfig resources with ignition version v3.2.0
Since openshift/machine-config-operator#3814, MCO writes v3.4.0 ignition configuration.
openshift/machine-config-operator@63d7be1 is the commit just before the culprit one.

Also, machine-config-operator@63d7be1ef18b86826b47c61172c7a9dc7c2b6de1
has a transitive dependency to `github.com/Microsoft/hcsshim@v0.8.7` that cause
a `go mod tidy` error:

```
github.com/Microsoft/hcsshim@v0.8.7 requires
k8s.io/kubernetes@v1.13.0 requires
k8s.io/endpointslice@v0.0.0: reading k8s.io/endpointslice/go.mod at revision v0.0.0: unknown revision v0.0.0
```
which is fixed in v0.8.8 by microsoft/hcsshim#783
