databases/cego: update 2.52.34 -> 2.52.36

• For CegoLogReader added stdin feature, so log file can be piped via stdin to cglog
• Extended backup list to indicate most recent redo log timestamp. For this, the backupManager utility had to be adapted to retrieve last redo log timestamp from arch and tape directory
• Added CegoXMLSpace::adjustPageOffset method to adjust page offset attribute after tableset recovery. This is needed, if a recovery is made from scratch with a new initialized database xml file
• Changed method CegoXMLSpace::nextTSID to generic. Instead of calculating the next tableset id on XML_MAXTSID_ATTR, the id is calculated based on all defined tablesets. In case of a from scratch recovery ( with a new initialized db xml file ), this ensures id consistency
