Instead of doing some dirs/files/links in launcher and some in
libzdtm, make everything in the launcher. The library is then
just to set up the namespaces.

If we get EBUSY here, it means that we didn't umount in the test (i.e. we
didn't call fini() on some path). We should just do that instead.

In current implementation of thread bomb effectively only one
thread runs, the rest sit in the read from pipe.
Fix this by making threads constantly creating new ones and

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.

It seems with the new zdtm.py that pids collide a lot more (perhaps because
everything is in its own pid namespace? not sure). In any case, this is
annoying as it prevents a second run of the tests from actually getting to
the test part.
So, let's try to move the old directory out of the way.

On debian/ubuntu systems, we don't have a /bin/env by default; on rhel
