Subject: [PATCH net-next v2 1/2] selftests: net: fix passive TFO test to fail if child processes failed

Improve the passive TFO test to report failure if the server or the
client timed out or exited with non-zero status.

Before this commit, TFO test didn't fail even if exit(EXIT_FAILURE) is
added to the first line of the run_server() and run_client() functions.
