Subject: [PATCH] docker/podman_sdk: Install sdk from deb when python
 externally managed

Since we're adding Ubuntu 24.04 that has python3.12 - we need to
install python3-docker/podman also there - future proof solution
is to check for existence of EXTERNALLY-MANAGED file.

Change-Id: Ibd2ab4379aac9cccf49d98b6bf3c12526eacdbd1
(cherry picked from commit 2ee3e850f13a0bcbe2b6a5e9d85847c13588bb26)
