test: assign result of print functions to temporary

Though I am not aware of any architecture where this matters, it
is technically incorrect to call these stdio functions as if they
had no result.

The QBE documentation says

> Unless the called function does not return a value, a return
> temporary must be specified, even if it is never used afterwards.

so we should follow it in the tests as well.
