jhbuild wrapper: don't muck with session activated services

dconf-daemon is available since 2.32, so there is no need to
start it manually (and in fact, it should not be running normally).
Similarly, notify-osd and notification-daemon should not be
dbus activated, but rather autostarted by gnome-session, and
therefore not running in a gnome-shell session.
