Change logs for powernap source package in Xenial

powernap (2.21-0ubuntu1) vivid; urgency=medium

  * debian/powernap.override:
    - only set the override as "manual" to really disable powernap under
      upstart
  * debian/powernap.postinst:
    - more elegant way to only strip the "manual" part (and removing the
      override if empty)
