util: update checkpoint aggregation script
The checkpoint aggregation script had become outdated due to numerous changes to checkpoints over the past couple of years. This updates the script. It now supports aggregation for x86 architecture instead of alpha. Also a couple of new options have been added that specify the size of the memory file to be created and whether or not the memory file should be compressed.
