kubectl: move translated data into kubectl

`kubectl cp` relies on tar to extract the copied file/directory in the
container, tar by default attempts to chown/chmod the extracted file
after extraction if the user is the "superuser"(root)

```
--same-owner
try extracting files with the same ownership as exists in the archive
(default for superuser)
-p, --preserve-permissions, --same-permissions
extract information about file permissions (default for superuser)
```

This fails in environment where the container runs as root but is not
granted the OWNER or CHOWN capability.

Before this patch below was the behavior of `kubectl cp`

```
kubectl cp README.md foo-67b6fcbd4c-qjlt6:/tmp
tar: README.md: Cannot change ownership to uid 1000, gid 1000: Operation
not permitted
tar: Exiting with failure status due to previous errors
command terminated with exit code 2
kubectl exec -it foo-67b6fcbd4c-qjlt6 -- ls -l /tmp/README.md
-rw------- 1 1000 1000 3179 Oct  7 22:00 /tmp/README.md
```

After this patch

```
kubectl cp -x a foo-67b6fcbd4c-qjlt6:/
kubectl exec -it foo-67b6fcbd4c-qjlt6 -- ls -l /tmp/README.md
-rw-r--r-- 1 root root 3179 Oct  7 22:00 /tmp/README.md
```

In some storage tests, kubelet is stopped first and the test check node
NotReady state. However, if it fails to have this state, kubelet could
not be restarted because the defer function is placed after the stop
kubelet command. This PR fixes this issue.
