evas: Ensure single init of common per canvas

After @cedric's commit 6427c77707fb6116a98b we end up with E
not working in Xephyr, because evas_common_shutdown() is called
too many times (init_count == -1). So I'm being paranoid and
tracking whether Evas has initialized or not evas_common. That
way we end up with exactly the right number of inits. We even
reach 0 after E shuts down :)
