grub-pc and grub-efi-amd64 conflict on Debian, so installing grub-pc at
build time removed the UEFI package. Keep grub-efi-amd64 in the image and
ship the matching grub-pc .deb under /var/lib/pve-maas/debs instead.
curtin-hooks installs it offline before builtin_curthooks when the node
booted in legacy BIOS mode; UEFI nodes are left as they are.
verify-image.sh now checks for grub-efi-amd64 and the stored grub-pc .deb
on amd64.
