The idea that each zdtm.py should have own helder, so that two zdtm.py that are
running on the same host don't effect each other.

Sometimes I get:
sudo ./zdtm.py run -t zdtm/live/static/cgroup03
umount: /home/tycho/packages/criu/test/zdtm.qPwsoO: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)
Traceback (most recent call last):
File "./zdtm.py", line 1401, in <module>
tst.available()
File "./zdtm.py", line 435, in available
subprocess.check_call(["flock", "zdtm_mount_cgroups", "./zdtm_mount_cgroups"])
File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['flock', 'zdtm_mount_cgroups', './zdtm_mount_cgroups']' returned non-zero exit status 1
let's use a lazy unmount so we avoid this.

This script prepares the cgroups hierarchies that are used by
tests to avoid creation of those in parallel with tests, that
do not expect them to appear.
