Add 'stats-dump' file to exported checkpoint
There was the question about how long it takes to create a checkpoint.
CRIU already provides some statistics about how long it takes to create
a checkpoint and similar.
With this change the file 'stats-dump' is included in the checkpoint
archive and the tool checkpointctl can be used to display these
statistics:
./checkpointctl show -t /tmp/cp.tar --print-stats
Displaying container checkpoint data from /tmp/dump.tar
[...]
