Subject: [PATCH] pylibfdt: Replace removed SWIG Python 2 compatibility macros

SWIG 4.5.0 removed Python 2 compatibility macros (PyInt_*, PyString_*)
from its runtime header pyhead.swg (see commit 79f7a2b7cb7d). Replace
them with their Python 3 C API equivalents:

- PyString_FromString -> PyUnicode_FromString
- PyString_AsString -> PyBytes_AsString
- PyInt_AsLong -> PyLong_AsLong

The replacements are safe since the macros were already aliased to
these exact functions in SWIG's Python 3 code path.
