[PATCH 1/2] doc: don't build notmuch-emacs.info for configure --without-emacs

[David Bremner <david@tethera.net>]

Since the docstrings are not built in the case of --without-emacs,
even if emacs is detected, don't let sphinx build the emacs docs. This
avoids a large number of error messages due to missing includes. It's
actually a bit surprising sphinx doesn't generate an error for the
missing include files.
