Modified the JSON output so that missing pins which do not match 

unconnected pins in the other netlist are marked as "(no pin)"
rather than "(no matching pin)".  This allows a script parsint the
JSON file (e.g., count_lvs.py from qflow) to distinguish between a
real pin error and one that can be ignored.
