databases/cego: update 2.38.1 -> 2.38.3

• Fix in CegoXMLSpace::setTSSortAreaSize, changed type from int to unsigned long long, otherwise overflow may occur for large sort area size configurations
• Performance optimization done in CegoOrderSpace. Instead of storing the CegoField list for the result tuple in CegoOrderNode, just the values are stored there. The order cursor now gets the schema with the constructor and build the CegoField List in the getFirst / getNext methods. This seems a huge amount of heap space, which is dynamically allocated during the sorting procedure ( sortareasize parameter ). Especially for large ordering result sets this saves significantly memory and improves performance.
