fix podman network prune integration test flakes

Browse Source 
The podman integration tests run in parallel. Because all tests use the
same CNI config dir the podman network prune test will remove networks
which are used by other tests at the moment and thus creating
unexpected flakes.

The solution use an extra cni config dir for the network prune test.
