always skip fmod shutdown, instead of just for release builds.

fmod shutdown has been a source of mystery crashes forEVER (go mine

materially different code behaviour depending on build type sucks as a
policy anyway, so always skip fmod shutdown.

straight-to-trunk to unblock(?) featurettes landing.
