Fix compiler warnings when X11 autolaunch and launchd are both disabled
From the department of "if it isn't tested, it doesn't work". I tried
compiling dbus without an assortment of optional features:
in_builddir ~/build/dbus/legacy ${MR_REPO}/configure \
--enable-developer --enable-maintainer-mode --enable-tests \
dbus_cv_sync_sub_and_fetch=no \
--disable-selinux \
--disable-inotify \
--disable-dnotify \
--disable-epoll \
--disable-kqueue \
--disable-launchd \
--disable-systemd \
--disable-libaudit \
--without-valgrind \
--disable-x11-autolaunch \
&& ...
and it resulted in -Wunused warnings.
