alsa-state: set up asound configs dynamically for verdin-imx8 boards

We need set up asound.conf and asound.state dynamitically at runtime
since the Verdin Development/Dahlia boards are using different ones.

To achieve that, we now introduce a on-target package postinst script
to set up them at runtime by checking /proc/device-tree/model to
determine which config files should be used.
