Add support for AVIRT
Leverage the new AVIRT driver for a more secure, more dynamically
configurable loopback sound driver.
To use, replace the file smixer-4a-default.json with
smixer-4a-avirt.json, at /usr/libexec/agl/smixer/etc
The existing snd-aloop configuration is not broken by this change.
The submodule libavirt is temporary, and will be transformed into a library.
