Serve web mixer at http://radxa-mixer.local on port 80

install.sh now sets the hostname (default radxa-mixer, --hostname or
--keep-hostname to override) after a successful install so Avahi
advertises NAME.local, and the web mixer listens on port 80. The web
server's host check already accepts HOSTNAME.local.
