Bug description:
  [Impact]
  Running 'sudo dmidecode' on non-UEFI ARM systems can cause them to crash/reboot. cloud-init apparently runs dmidecode as root, so it breaks any cloud-init based installation.

  [Test Case]
  sudo dmidecode

  [Fix]
  Upstream has the following fix:

  commit e12ec26e19e02281d3e7258c3aabb88a5cf5ec1d

      dmidecode: Only scan /dev/mem for entry point on x86

  [Regression Risk]
  In Ubuntu, dmidecode only builds on amd64, arm64, armhf & i386.
  The fix is to disable code on !x86, so the regression risk is restricted to ARM platforms, where we know /dev/mem trolling is bad news.
