birdnet-go: ship ALSA overrides at /root/.asoundrc

Browse Source 
/etc/asound.conf is read-only in the addon environment, so both the
shipped overrides and the user-supplied override are now written to
/root/.asoundrc (the app runs as root with HOME=/root). ALSA loads
~/.asoundrc as an additive layer on top of the system config, so the
override behavior is unchanged.
