Incorrect scoring of seki eyes with Chinese rules

Description

In this position









black has an eye in the seki. With Japanese rules there's no territory at all in the lower left but with Chinese rules black is allowed to count the false eye at C1.

Unfortunately the aftermath scoring ("--score aftermath" or final_score in GTP mode) doesn't score seki eyes correctly with Chinese rules and instead disregards them like in the Japanese case.

The attached patch fixes this mistake. An sgf of the position above is also attached.
