Remove the timestamp_ member of StreamGenerator.

timestamp_ is only used in GenerateFrame() and its old value is
discarded. So it just needs to be a local variable in GenerateFrame().
As a result, we can remove the start_timestamp parameter from the
constructor and Init().

Also mark the GeneratePacket() method private because it is only used
internally.
