What this PR does / why we need it:
In many of our applications, we create a symbolic link to kubelet. But lsattr -laR /var/lib/kubelet would raise an error something just like lsattr: unspported operation While reading flags on xxx. This can be easily solved by adding a directory flag /.

Hi @KubeKyrie. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
