tests: remove 001-policy-enforcement.sh test
tests: remove 001-policy-enforcement.sh test

Given that we have moved to a single policy enforcement default behavior model
as part of #1464, there is no need to have both
tests/14-policy-enforcement-docker.sh and
tests/k8s/tests/001-policy-enforcement.sh run as part of our CI.
Given that Kubernetes tests take a longer amount of time, in order to reduce
the build time, we should remove tests/k8s/tests/001-policy-enforcement.sh
as tests/14-policy-enforcement-docker.sh covers the testing of this behavior.
