Rename hassos to haos (#1213)

* Change HASSOS_ID from hassos to haos

Use a rauc install-check hook to make this update compatible with OS
releases using hassos in the compatible string.

* Use home-assistant as organization in CPE_NAME

Align with Home Assistant core which uses home-assistant with a dash as
organization in CPE_NAME.
