package/avahi: fix python install issue

Since the update of Python to 3.12.4 in commit
76cd14167f5eb3ffe22e131ddbbecf9bc61f2ef1 avahi fails to install
python subcomponents. The reason is that the obsolete imp
python modul is used. Add a patch to remove the imp dependency.

+Remove optional imp python module dependency.

+Upstream already removed py-compile entirely in their git repository,
+so the patch is not appropiate for upstream.
