dummy audio driver does not work on emscripten about sdl HOT 6 CLOSED

So I haven't looked at this, but I can already say that every audio backend uses a thread by default unless it takes measures to provide its own...the emscripten backend uses a function that runs between iterations of the mainloop to get around this.

We could add an emscripten-specific similar thing for the dummy driver is this is useful, but it's probably better to just disable the test.

(Even the dummy backend needs to consume audio at a regular interval and provide silence on recording devices, so it still needs a thread.)

This is fixed now, as of d118af5. Beyond the test, there are probably some small special cases where it's useful for people to be able to build Emscripten builds with only dummy audio, or for a user to override a page with ?SDL_AUDIO_DRIVER=dummy on the URL, so I plugged this in.

Thanks!

To be honest, I wasn't sure about the need for this one.
