[Bf-cycles] Remove old Sky Model

[Piotr Adamowicz]

Since Sergey mentioned there were not enough artists on the list -

The removal of the old sky shader is no problem. Should there ever be
a need to render an old scene with the old sky in a new Blender
version, it's trivial to render the sky out to an environment texture
with an older Blender version. So IMHO it's fine to remove it for 2.8.
