[OE-core] Qemu-native requires alsa-libs-native

[Zhai, Edwin]

Koen,
We enabled alsa in configure for the feature of receiving sound from 
guest. It is assumed that audio system on host is already enabled.

I'm not sure if we need add alsa native, given that they are host 
specific. Besides alsa, we also need sound card driver on host, which is 
beyond the scope of our build system.
Maybe, we can check alsa lib first, and enabled "--audio-drv-list=alsa" 
after finding it. Or we can document alsa as build prerequisite?
