  v.perturb: If vector map is 3D, preserve the z coordinate (#1660)

* This checks if the input map is 3D and if yes, makes the output 3D too.
* The Z coordinate is not modified.
* This follows 2.5D design. Z is considered special, so not perturbed. However, Z is now not lost.
* A future change can add a flag to perturb also Z without a change of interface or behavior.
