What this PR does / why we need it:

The Docker Option is not work in centos arm64 platform. Because of it use error cgroupdriver.

The code is added in #2168 in 2018. The cgroup driver is cgroupfs in x86 , and systemd in arm64.

And the default docker_cgroup_driver has been to systemd now. It's the same between arm64 and x86 now. So we should remove these code.

I have tested the change in ARM64 machine.

Hi @yankay. 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.
