Have the seek-read routines take a Buffer rather than a guint8 pointer

as the "where to put the packet data" argument.

This lets more of the libwiretap code be common between the read and
seek-read code paths, and also allows for more flexibility in the "fill
in the data" path - we can expand the buffer as needed in both cases.
