tests: Add helper for TIOCSTI exploit
This helper/exploit injects "id -u -n\n" to the vulnerable calling terminal. Use id -u -n to get a reproducible output of test cases based on it. What can happen: Nothing, no exploit: pty is not accessible, sedsid() disconnected the task from pty, TIOCSTI failed. The command is injected to the unprivileged environment pty, and you see e. g. "nobody": This is acceptable. The command is injected to the caller (privileged) pty, and you see "root" (or caller uid name): This is not acceptable and has security implications.
