Add missing environment for a couple of tasks

If564089fb1cb77366fa6d6f8e4086691a4dfcf37 introduced a new parameter,
allowing to disable container validation by setting the
SMDEV_CONTAINER_OFF environment variable.

A couple of places were overlooked, leading to issues, especially in a
satellite-6 enabled environment.
