build: Move from our own containerd to containerd.io

Let's migrate to the official containerd package from
docker repository and no longer build and maintain our own
containerd package.

Due to this change, downgrade is not supported from 133 to 132,
it could be possible to handle this case but it would require
extra work to downgrade containerd and config before running
the downgrade since "old" salt states cannot be used to perform
this downgrade since `containerd.io` version we install "obsoletes"
the `containerd` version we have in older version.

That's why we decided to not support this downgrade path.

Fixes: MK8S-151
