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.
