Bug description:
  [Impact]
  fwupd does not load, can't upgrade firmware

  [Test plan]
  Try reinstall a firmware upgrade, make sure fwupd loads. Make sure you use secure boot. It's OK testing this in one release, as the fix is entirely shim-side and it's binary-copied.

  [Where problems could occur]
  We might fail to boot from BIOS generated boot entries, as in bug 1937115

  [Original bug report]
  I am running hirsute on Thinkpad X1 Carbon gen 7. Fwupdmgr used to work on groovy. Now, fwupdmgr detects new firmware, successfully places the .cap file in /boot/efi/EFI/ubuntu/fw/, successfully sets efi "next boot" to 2 which is "Linux-Firmware-Updater", but on reboot, there are no signs that fwupdx64 was attempted to be executed, and system drops directly into grub.

  Same when I use BIOS boot menu. There are entries for "ubuntu" and for
  "Linux firmware updater", but selecting any of them boots grub.

  After boot, EFI "BootCurrent" points to the updater entry, though it
  apparently did not run!

  $ efibootmgr -v|head

  These sympptoms match precisely a previous bug:
  https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1864223

  Could it be that the fix introduced then was lost, maybe due to
  signing schedule?

  There is a github ticket https://github.com/fwupd/firmware-lenovo-
  thinkpad/issues/123 that could be explained by this problem too.
