#7351: BGameSoundDevice is broken on hybrid installs

The BGameSoundDevice class is at te core of the sound part of the game
kit. This class creates its own mixer and does not use the system one.
According to a TODO in the code, this is bad practise.
On a gcc2h system, a gcc4 compiled app will not work, because :
* The app is linked with libgame, which itself links libmedia
* This class tries to create a mixer, which loads the mixer add on
As a consequence, the (gcc2) mixer add-on gets loaded in a gcc4 app. This
does not work.
{{{
BMediaRoster::InstantiateDormantNode: addon-id 6, flavor_id 0, flags 0x0
resolve symbol "__tf11BTimeSource" returned: -2147478780
DormantNodeManager::LoadAddon: loading "/boot/system/add-
ons/media/mixer.media_addon" failed: Symbol not found
DormantNodeManager::GetAddon: can't load add-on 6 from path /boot/system
/add-ons/media/mixer.media_addon
BMediaRosterEx::InstantiateDormantNode: GetAddon failed
}}}
This makes the whole BGameSound stuff basically unuseable in hybrid
systems. The fix is to remove this mixer from the class, or to make it use
a gcc4 one when needed (like we do for translators addons).
