[gnome-weather] Fix distcheck

[Giovanni Campagna <gcampagna src gnome org>]

commit 512d42c98bb52ed6fcbe676f9c6c732cfffe0066
Author: Giovanni Campagna <gcampagna src gnome org>
Date:   Tue Mar 5 15:51:51 2013 +0100

    Fix distcheck
    
    - Add missing files
    - git.mk must be included with -, or automake adds it to the distribution,
      causing it to run in tarballs (which breaks)
