[Buildroot] [git commit] package/containerd: add control for additional build tags

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=6122ba62f6d9ac4350b9bb2e5d935acfd077e2c9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Disable the AUFS snapshotter by default. AUFS support has been deprecated
since v1.5 and won't be available with containerd v2.0.

Add configuration option for the ZFS snapshotter and add the proper
runtime dependencies.

Add configuration option for Kubernetes CRI support. Note that CRI
support requires a writeable /etc or an appropriate containerd
configuration.
