Bump CNI to v1.0.1

Update CNI so we can match wrapped errors. This should silence ENOENT
warnings when trying to read the cni conflist files.

Fixes #10926

Because CNI v1.0.0 contains breaking changes we have to change some
import paths. Also we cannot update the CNI version used for the
conflist files created by `podman network create` because this would
require at least containernetwork-plugins v1.0.1 and a updated dnsname
plugin. Because this will take a while until it lands in most distros
we should not use this version. So keep using v0.4.0 for now.

The update from checkpoint-restore/checkpointctl is also required to
make sure it no longer uses CNI to read the network status.

[NO TESTS NEEDED]
