OK so I got xenial compiling by a few extra backported patches.  I've
uploaded fwupdate and fwupdate-signed for xenial to proposed.

Bug description:
  [Impact]

   * A few users have reported instances of not being able to boot into Ubuntu after a firmware update.  This is suspected to be caused by a missing Ubuntu boot entry.
   * fwupdate adds an entry for doing the update to the BootOrder, but doesn't remove it.  BIOS auto-creation for making boot entries typically depends on the BootOrder being empty.

  
  * This affects all releases of fwupdate since the code to add to BootOrder was
  also backported into the Ubuntu 16.04 release of fwupdate (0.5-2ubuntu5)

  [Test Case]

  * Perform a UEFI BIOS update after installing this package.
  * Ensure the system boots and there is no longer a "Linux Firmware Updater" entry
  present in the efibootmgr -v output.

  
  [Regression Potential] 

  * Regressions are possible to manifest if any BIOS depends on the
  previous behavior.

  * The fixes that were backported have been upstream for a few months and no
  concerns have been raised upstream from them.

  [Other Info]
  Two users have reported that fwupd breaks their Ubuntu installation because the "Ubuntu" EFI boot option disappears after an update.
