[cr_tests PATCH 1/1] process-tree tests: several changes

Make the freeze() function work right.
Use ns_exec -g and drop the use of ns cgroup.
Don't restart with ns_exec. Use mktree --pids and --pidns
to create pidns.
run-ptree1.sh now passes for me. run-pthread1.sh does not
(checkpoint: Resource temporarily unavailable).
