BGameSound: make Worms Armageddon sounds work

* When the endianness is not intialized, assume B_MEDIA_HOST_ENDIAN.
This is probably what was meant (and this is what Worms Armageddon
means).
* Move creation of the media nodes back to the initialisation instead of
StartPlaying, otherwise an extra node is created each time the sound is
played.
