databases/cego: update 2.49.10 -> 2.49.11

• Patch added for memory leak in CegoSelect::cleanUp and CegoSelect::reset, for both methods, _pCacheList has to checked and freed, since for uncompleted queries ( e.g. exists clause ) the _pCacheList was still not deleted
• Another fix for memory leak added in CegoFieldValue::getLocalCopy, Before allocation, _len has to be checked for _len < STATICFIELDBUF and then use _staticBuf, otherwise, the memory is lost
