Removal and exchange duplicate test for privileged containers

[horecoli]

Description

This change removes the Kubescape implementation of test for privileged containers. The reason behind this decision is the absence of functionality to exclude containers from the test. Instead, it has been replaced with an in-house implementation of this test, which has been renamed from "privileged" to "privileged_containers".
