Ok, will send ASAP.

For moving the process out of the process group setpgid() is enough, we
use it in the lib/tst_test.c for the fork_testrun() in order to track
all children of the test process as well.

I do not think that we need a new session here, that would probably have
strange side effects, for instance it would isolate the tst_timeout_kill
process from the terminal the tests were started in.
