The ns and uns flavors are MUCH better ways of launching tests in namespaces.

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.

This change does two things to be more defensive: 1. add a checkskip script
which fails if __NR_seccomp isn't defined, and 2. allows
seccomp_filter_tsync to compile even if it isn't defined (and then fails
"gracefully" with a skip message if it does).
The checkskip bits are necessary because zdtm.sh gets confused if the test
exits 0 without actually invoking criu.

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
just exiting.

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.

There are tests (e.g. on locks) that can conflict with each other, so
wait for all the other jobs to finish before running such.

Wait for the excl test to finish before launching more of them.
