avserver: remove daemon mode
This code spews a multitude of warnings with glibc (unchecked return values), some of them possibly warranted. Furthermore, the deamonisation is not suitable for use with typical startup scripts as it does not provide the PID of the daemon in any way. Users wishing to run avserver as a daemon can still do so using start-stop-daemon or equivalent tools.
