dummyaudio: Remove bitrotted support for __EMSCRIPTEN_PTHREADS__ code path.

Browse Source 
In SDL_audio.c:OpenPhysicalAudioDevice, an attempt is made to SDL_CreateThread
if ProvidesOwnCallbackThread is false, but SDL_CreateThreadWithPropertiesRuntime
is not implemented for Emscripten, so this always fails. I'm not sure if/when
this ever worked, but it simply cannot work in its current state.
