victara: Move libspeakerbundle to soundfx

It needs to be here if I am going to be able to use the same
library for the external speaker extension in the audio hal.

victara: Clean up audio board flags

* Correctly enable FLUENCE (it was using the MSM8960
* Remove flags that were enabling already enabled functionality
* Remove flags that are not in the msm8974 hal (left over from ghost)
* Disable speaker protection in the build because we were disabling
  it in build.prop anyway.
