Node E2E: Reorganize node e2e output directories.

Fixes https://github.com/kubernetes/kubernetes/issues/35074.

This PR cleans up the result directory and workspace directory of node e2e test.

Local result directory:

```
/tmp/_artifacts/
        |----- build-log.txt  (build log)
        |----- *.xml  (junit xml file)
        |----- local/  (local run *.log)
        |----- hostname1/  (remote run *.log)
        |----- hostname2/
```

Workspace directory on test node:

```
/tmp/node-e2e-yyyy-mm-ddThh-mm-ss/
        |----- cluster/  (gci mounter)
        |----- cni/  (cni binary)
        |----- e2e_node.test  (test binary)
        |----- e2e_node_test.tar.gz  (test tar)
        |----- etcd060429031/  (etcd data directory)
        |----- ginkgo  (ginkgo binary)
        |----- kubelet (kubelet binary)
        |----- pod-manifest365096781/  (mirror pod directory)
        |----- results/  (test result directory)
```
