To prevent loss of config when grub-pc is updated and the user naively
chooses to take the maintainer's version any intelligent modifications
done during installation will be lost.
Instead we take advantage of the fact that the grub-pc package in
Debian since tag 2.00-10 contained some version of reading
/etc/default/grub.d/*.cfg to read additional configuration without
triggering a ucf missmatch.

Please consider this for backport to Jessie, I was able to cherry-pick
this patch cleanly on top of version 1.117+deb8u1. Also of note I only
tested with a rebuilt Jessie installer using monolithic and localudebs
version of grub-installer udeb.
Thanks!
