trau_sync: prevent false positive synchronization on startup

The history buffer is filled with zeros on startup. Together with
incoming bits those may appear as a valid signal. (each trau frame
begins with 16 zeros). In order to prevent this lets set the history
buffer to all ones, so that it looks like the data in the history
buffer is from an unused timeslot.
