ao_opensles: set numBuffers to 8

Browse Source 
Apparently some Android builds/forks require this for Bluetooth
audio to work as they unexpectedly accept fast flag for it.

Shouldn't cause any side-effect (e.g. buffer requirement increased
when on wired audio). It's a hardcoded default in the upstream
AAudio implementation anyway.
