uboot-sunxi: fix build with swig 4.3.0

Swig 4.3.0 has changed SWIG_Python_AppendOutput, which now requires an
additional parameter `is_void`. SWIG_AppendOutput remains unchanged.
This was fixed upstream in u-boot/u-boot@a63456b

```
scripts/dtc/pylibfdt/libfdt_wrap.c: In function '_wrap_fdt_next_node':
scripts/dtc/pylibfdt/libfdt_wrap.c:5581:17: error: too few arguments to function 'SWIG_Python_AppendOutput'
 5581 |     resultobj = SWIG_Python_AppendOutput(resultobj, val);
      |                 ^~~~~~~~~~~~~~~~~~~~~~~~
```

This is the same fix as applied in 363e07d.

+Subject: [PATCH] scripts/dtc/pylibfdt/libfdt.i_shipped: Use SWIG_AppendOutput
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Swig has changed language specific AppendOutput functions. The helper
+macro SWIG_AppendOutput remains unchanged. Use that instead
+of SWIG_Python_AppendOutput, which would require an extra parameter
+since swig 4.3.0.
