This enshrines the current testsuite practice of using ffi_arg for
returned values. It would be reasonable and logical to use the actual
return argument type as passed to ffi_prep_cif, but this would mean
changing a large number of tests that use ffi_arg and all backends
that write results to an ffi_arg.
