Make inferior/GDB share terminal in tests expecting output after detach

A following patch will make GDB put spawned inferiors in their own
terminal/session.  A consequence of that is that if you do "run", and
then "detach", GDB closes the terminal, so expecting inferior output
after detach no longer works, the inferior is alive, but its output
goes nowhere.

There's only one testcase that expects output out of an inferior after
detach.  Tweak it to output to GDB's terminal instead.
