Bug description:
  [Impact]

   * Image builds take time
   * Some of the time is spent computing checksums
   * Those checksums are never used
   * Time and energy is wasted
   * build/(md5|sha256)sum.txt is not used by livecd-rootfs and not exposed by launchpad-buildd

  [Test Case]

   * Build images
   * Disable checksums
   * Build images
   * Ensure image deliverables are unchanged

  [Regression Potential]

   * Someone was using the checksums outside of launchpad-buildd; because launchpad-buildd doesn't present those artifacts
   * The checksums are included beside the squashfs in live-build ISOs but none of our projects use live-build to build ISOs.
