vendor: bump runc to latest, fix performance regression

[kolyshkin]

This is a test in preparation for runc rc94 release, to make sure
there are no regressions.

In particular for cadvisor, rc94 fixes cgroup manager's GetStats
performance regression (opencontainers/runc#2921).

Hi @kolyshkin. Thanks for your PR.

I'm waiting for a google 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.
