Fix U-Boot build issue with Swig 4.3.0

Tested on Debian Sid, as of 30 December 2024, which uses
Swig 4.3.0. Context here:

commit a63456b9191fae2fe49f4b121e025792022e3950

    scripts/dtc/pylibfdt/libfdt.i_shipped: Use SWIG_AppendOutput

This patch from U-Boot upstream has been backported to the
release revision used by Libreboot. Swig has, since 4.3.0,
changed the language-specific AppendOutput functions, but
the helper macro SWIG_AppendOutput is identical; therefore,
upstream switched to this function.

The benefit of this fix is that since the newly used macro
is also the same on older Swig versions, and behaves the same,
this shouldn't fix building on older Swig versions. For reference,
the initial Libreboot 20241206 release, and revisions of it before
revision 8, was built on Debian 12 which uses Swig 4.1.0.

The rev8 release will still be compiled on Debian 12, but with
this change, it should also compile on Debian Sid, and bleeding
edge distros like Arch Linux.
