babeld: update to 1.13

Announcement:
https://alioth-lists.debian.net/pipermail/babel-users/2023-July/004100.html

Babeld removed diversity routing [0], so we need to adjust ubus
bindings. Further. we need to add a patch that makes local_kind
accessible again: "100-local-make-local_kind-function-accessible.patch"

Refresh patches:
- 600-add-ubus.patch

+Subject: [PATCH] local: make local_kind function accessible
+
+The kind-definitions are contained in the header file:
+  LOCAL_FLUSH 0
+  LOCAL_ADD 1
+  LOCAL_CHANGE 2
+
+The function (local_kind) that converts them into strings again
+is private. New addons (for example openwrt ubus bindings) that make
+use of babeld should also use the same function to convert the kind
+to string format. This allows to ensure uniformity over all addons.
