news: Document removal of support for .ini style of comments

In previous patches virKeyFile was replaced with its GLib
counterpart which created an incompatible change: comments can
now begin only with a number sign (#). While this won't probably
affect anyone, mention it in the release notes.

+          With switching of our internal code to GLib, parsing of client
+          authentication config files is handed over to GLib which does not
+          support <code>INI</code> style of comments starting with a semicolon
+          (<code>;</code>). Use number sign (<code>#</code>) instead.
