fix: add missing runc/containerd deps from python slim

[brettlangdon]

In some docker-in-docker situations we get failures such as:

WARNING: Event retrieved from the cluster: Error: failed to create containerd task: failed to create shim task: ENOENT: No such file or directory
Stack backtrace:

Likely from missing containerd from the move to the python slim base image.

This increases the image size from around 460mv to about 500mb.
