libdnf: backport patch to fix segfault

This is needed to allow libdnf to build OK with python 3.13.1. Without
it, a vague "Could not invoke dnf" error is seen during rootfs (e.g.
when building core-image-full-cmdline), with a return code of -11.

+Subject: [PATCH] Fix a segfault in iterator of a ConfigParser section
+
+An iterator should return self on __iter__.
+
+So that this works:
+
+    >>> it1 = iter(sectObj)
+    >>> it2 = iter(it1)
+    >>> it1 is it2
+    True
+
+Previously, this iterator did not return self on __iter__, it was like this:
+
+    class PreserveOrderMapStringStringIterator(object):
+        ...
+        def __iter__(self):
+            return _common_types.PreserveOrderMapStringStringIterator___iter__(self)
+
+And that returned a new Python object.
+
+This fixes https://bugzilla.redhat.com/2330562 by avoiding a second iterator object.
+
+My SWIG skills are close to zero,
+perhaps this is not the best way to return self, but it seems to work.
+
+Upstream-Status: Backport
+(https://github.com/rpm-software-management/libdnf/commit/f3302a865b)
+
+Backport so that it works properly with Python 3.13.1.
