tests: Fix interactive test without libreadline.

When using actual readline, the user's input is echoed internally, so
the test case sees the actual input commands in the captured standard
output.  But in the getline-based fallback, the input is not reflected
to the output.  This is expected behaviour, but confuses the test case.

Rewrite the check to accept either form.
