This moves to using a single revision of pkgs. It includes a few changes: - kernel with KVM host support - containerd v1.3.0 This change brings in a kernel with host KVM support. This will allow us to use VMs within Talos for things like integrations tests. This also allows users to do things with KVM as they see fit. Signed-off-by: Andrew Rynhard <andrew@andrewrynhard.com>
