Cycles: Fix bump mapping to use object space when used with true displacement

Bump mapping was happening in world space while displacement happens in object
space, causing shading errors when displacement type was used with bump mapping.

To fix this the proper transforms are added to bump nodes. This is only done
for automatic bump mapping however, to avoid visual changes from other uses of
bump mapping. It would be nice to do this for all bump mapping to be consistent
but that will have to wait till we can break compatibility.
