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.
