executes /host/usr/bin/oc

https://github.com/openshift/cluster-network-operator/blob/830daae9472c1e3f525c0af66bc7ea4054de9989/bindata/network/openshift-sdn/sdn.yaml#L308
is executing the host's `oc` but in a container userspace. This breaks when we try to update RHCOS to RHEL9, but leave the SDN pods as rhel8.

This code looks likely better to directly write in Go instead of bash.
