Bug description:
  [Impact]
  Any ARM64 GRUB image that includes the setjmp module will fail, reporting an "incompatible license" error. Ubuntu doesn't normally include this module in most images. The one exception I know of is MAAS which, by default, includes all modules when generating EFI images. MAAS currently has a hack to blacklist setjmp on arm64 because a fix wasn't available at the time - but I fear other users will try to do the same thing and hit this issue which can be difficult to track down.

  [Test Case]
  PXE boot a grub image on arm64 that includes the setjmp module:

  $ grub-mkimage -v -o grubaa64.efi -O arm64-efi -d
  /usr/lib/grub/arm64-efi setjmp

  [Regression Risk]
  The patch merely adds a license section to the module and it has been tested to work.
