A few games (Sfinx, Inherit the earth/German,
Zork Grand Inquisitor, Zork Nemesis)
only work with scummvm (>= 1.8.0).

While this precise release is due soon, GDP should catch
this error early and not at the 'dpkg -i' stage.

Tricky: this has to be done by package, not by game,
as the English version of "Inherit the earth" works
with older scummvm releases.

Easy part is done, tricky not yet, keeping this bug open;
but lowering severity as only 1 package is impacted
for 1 month or 2 and this is explained in help_text too.
