Fix T40364: Texture images are not properly displayed in the material preview in BI when using SSS

Blender Internal only uses materials with non-zero user counter for SSS and new
mutable libblock copy was keeping users counter at zero.

Now it sets user counter to 1, which is a bit of arguable decision, but which
also kind of makes sense -- meaning callee owns the copied block.
