Fix support of the latest kubelet version.

Created by: garloff

apt-cache policy reports the latest version with *** prefixed. We need to remove them (sed 's/***//') before using awk's pattern matching, so it has a hit.

Better would be to do it in one (fixed) awk call, but my sed skills are much better than my awk skills

This fixes issues #104 (closed).

Being at it: containerd.io is containerd now.
