Increase port-forward timeout to 1s to fix e2e test
Increase port-forward timeout to 1s to fix e2e test

We encountered two failing end-to-end tests after the adoption of
https://github.com/containerd/cri/pull/1470 in
https://github.com/cri-o/cri-o/pull/3749:

```
Summarizing 2 Failures:
[Fail] [sig-cli] Kubectl Port forwarding With a server listening on 0.0.0.0 that expects a client request [It] should support a client that connects,
sends DATA, and disconnects
test/e2e/kubectl/portforward.go:343

[Fail] [sig-cli] Kubectl Port forwarding With a server listening on localhost that expects a client request [It] should support a client that connects
, sends DATA, and disconnects
test/e2e/kubectl/portforward.go:343
```

Increasing the timeout to 1s fixes the issue.
