package/firewalld: backport Python 3.13 port

The module pipes is no longer part of the Python standard library. It
was removed in Python 3.13 after being deprecated in Python 3.11. The
last version of Python that provided the pipes module was Python 3.12.

Our firewalld 2.0.2 version is now superseded by several releases
(up to 2.3.1) that include this patch (since 2.1.0).

+
+Since Python 3.3, shlex.quote() replaces it. This avoids a deprecation
+warning.
