Avoid copy of encryption-provider from drbd location

As we are using secure luks file system which is replicated
as well between controllers. We don't need to copy it from
drbd config location in controllerconfig service.

This change avoids copy of encryption-provider.yaml from
'/opt/platform/config/<version>/kubernetes' to
'/etc/kubernetes'. This fixes the issue observed during
platform upgrade.

Test Plan:
PASS: build-pkgs -c -p controllerconfig
PASS: build-image
PASS: SX upgrade: system should be upgraded to the latest version
      without any issues.
