Dual porosity: Shift K-layer to fracture section for completion export

For dual porosity models, the first N K-layers represent MATRIX and
K-layers N+1 to 2N represent FRACTURE. Shift K to the fracture section
at production points so exported completion data (COMPDAT, WPIMULT,
COMPLUMP, COMPSEGS) references the correct K-layer. Subtract the offset
in LGR bounding box computation where original grid K is needed.
