Stop using --memory for cgroup v2.

[hetong07]

Fixes #10371.

Disable --memory option for cgroup v2, since cgroup v2 does not allow setting memory.

minikube start would throw an error as below

Hi @hetong07. Thanks for your PR.

I'm waiting for a kubernetes 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.
