databases/cego: update 2.33.9 -> 2.33.11

• Fix in CegoObjectManager::createBTreeObject to avoid some duplicate btree entries
• Added space character in CegoSelect::toChain after distinct keyword to avoid certain errors
• Fix in CegoAttrComp::operator== The values should NOT be compared, since they are set up by the calling CegoAttrCond::update method Otherwise, the error "Cannot set up diff for attribute condition" occurs. basecheck54 added to test for the this problem
• Fix in CegoQueryHelper::evalAttrCond, comparison modulation was missing for one case whihc leads to wrong query results for comparisons like 3 < a ( constant left )
• Optimization added for between clause, indexes were just used for constant values in between clause ( eg. a between 10 and 20 ) This has been expanded, that also indexes are used, if attribute references are contained ( eg. a between t2.x and t3.y )
