alfred: Start up alfred without valid interfaces

The alfred server always needs interfaces to operate on. But these
interfaces might not exist at the moment when the daemon process is
started. This situation stopped the startup process after the init scripts
waited for a longer period of polling the system state.

But alfred is able to deal with interfaces which disappeared at runtime but
existed at startup. To force a similar behavior for the alfred startup, the
parameter "--force" or "-f" is used. The extra polling code is therefore no
longer needed in the init scripts.
