    build: enable running autoreconf on tarballs
    
    A couple of things were preventing autoreconf from working properly on
    our tarball releases.  Fix those up:
    
     - the m4/ directory (with intltool and gtk-doc m4) was not being disted
    
     - our ./autogen.sh invoked automake with --foreign, suppressing
       warnings about missing ChangeLog, etc.  Move that flag into
       configure.ac so that they are still suppressed when using autoreconf.
