linuxnamespaces.run_in_fork: use os._exit instead of sys.exit
When using sys.exit, we actually raise a SystemExit exception and as a consequence exit all context managers. If a particular context manager pertains only the process at hand, we don't really care, because our process is supposed to vanish. If a context manager changes external state such as tempfile.NamedTemporaryFile, this is very bad and unexpected. We need to ensure that such cleanup is not performed. This also simplifies the test suite that had to emulate this behaviour already as pytest uses a context manager.
