Use dpkg-divert to move /usr/sbin/update-grub aside and replace it with
a dummy script.  The GRUB packaging only ever calls grub-mkconfig via
update-grub, and if the latter is diverted using dpkg-divert then that
will persist across upgrades.

This is much less intrusive than dummy packages or anything like that.
