Depsgraph: Fixes for render pipeline building

- Need to assign current scene in the builder: it is used to
  route relations for object's customdata.

- Tweak relation from scene to object for the customdaat: this
  didn't work before because the render pipeline scene has no
	view layer component.

Fixes T65044: Crash when Rendering (F12)
