@kochstefan pointed out that asterisk 15 doesn't load any modules. It
turned out that this happens because of patch that was dropped. Add the
patch again.

I introduce asterisk 15.x as a replacement for asterisk 11.x. Currently
without support for chan-lantiq and sccp-b. Those features are going to
be added soon after this introduction.
