tests: Fix race condition on cancellation in unix-streams test
The cancellable may be cancelled just after the operation succeeds in a
different thread. So instead of checking whether the cancellable is
cancelled, check whether the operation returned a `CANCELLED` error, and
*then* assert that the cancellable is cancelled.
This should fix
