libglvnd in unstable

[Andreas Beckmann]

Hi Luca,

I just noticed that libglvnd arrived in unstable. If you have time, I
would be interested in hearing about tests using these libraries instead
of lib*-glvnd-nvidia*. There is no libgles1* (mesa has dropped it as
well), but I think we should keep it for now, especially since we will
use these packages for stretch and we shouldn't drop stuff without need
from stretch. I'll probably drop it once nvidia forks off a new legacy
lts branch (because thereafter we will stick with that branch for stretch).
