test(cli): the terminal tests speak BSD script on macOS; a noted root is compared as the system spells it

The portable macOS job, now past the server start: `script -qefc` is
util-linux's spelling; macOS's BSD `script` has no -f and no -c, so the
three pseudo-terminal helpers choose the spelling for the OS. And the
root noted "for next time" is the canonical path (macOS writes /tmp as
/private/tmp); the test compares it canonically.
