databases/cego: upgrade 2.44.9 -> 2.44.10

• Fix in CegoAction::readChain() to support "\r" escape character Fix in CegoBTreeCursor::getFirst, in case of pAttrCond = 0, getNext has to be called if current leaf page is empty, otherwise cursor trace is incomplete ( just used for CegoDistManager::verifyTable )
• Fix in CegoBTreeNode::getChildPage, parameter traceMin has been introduced, which is needed to trace btree with CegoBTreeManager::deleteBTree. Otherwise, it might happen that non-unique btree objects are not found
