This should catch installations from our ISO on non-ZFS in uefi mode, which won't get the updated grub efi binary installed upon upgrade, because grub-pc is installed instead of grub-efi-amd64. Adding this to pve7to8 should make this even more visible, than the corresponding patch for promxox-kernel-helper (warnings printed during regular package upgrades might be overlooked more easily than a yellow line in the major upgrade checkscript) The if/else order was chosen to limit the nesting level of the long messages.
