zdtm.py: Ability to generate criu strace-s for sat.py

Browse Source 
There's a sat.py script in criu-scripts repo that analyzes the strace
outputs. It's useful to check the amount of system calls criu takes to
do dump or restore of certain apps.

So add the --sat key to zdtm.py that would generate sat-able logs for
individual tests.
