[8.x](backport #6016) Remove endpoint security from linux containers

[mergify]

• Enhancement

What does this PR do?

The goal of this implementation is to remove endpoint security from linux containers. Since we currently do not distribute any container other than linux containers (source), this PR does not consider selected platforms when excluding the endpoint security from container images.

Why is it important?

Endpoint security cannot run in containers since it has a systemd dependency.
