do-not-merge: tests/cri-containerd: temporarily use containerd fork with getRuncOptions fix

The cri-containerd integration tests fail with the shim sandboxer when
running non-runc runtimes (e.g. Kata). The root cause is a bug in
containerd's client/task.go: getRuncOptions() unconditionally tries to
unmarshal the container's stored runtimeOptions into containerd.runc.v1.Options,
but Kata containers store runtimeoptions.v1.Options. This causes:

  failed to create containerd task: failed to get runtime v2 options:
  can't unmarshal type "runtimeoptions.v1.Options" to output
  "containerd.runc.v1.Options"

A fix has been submitted upstream. Until it is merged and released,
clone containerd from the fork that carries the fix so that
`make cri-integration` (which builds and runs its own containerd daemon)
picks up the corrected binary.

TODO: revert once the fix is in an upstream containerd release and
versions.yaml is updated accordingly.
