Pierre Bourdon 2c1c538fda Disable the OpenAL and Pulseaudio audio backends
They are currently broken and cause sound issues which are not present in other
backends:

* OpenAL plays music 2x too fast in Zelda UCode games with HLE
* Pulse backend uses a lot of CPU power and slows down emulation significantly

Both backends are currently being re-implemented in separate branches of
Dolphin, so this should be a temporary removal.
