android: jpeg: Pass StreamBuffer to Encoder::encoder

To prepare for support of the JEA encoder in a following commit, which
will need to access the buffer_handle_t of the destination buffer, pass
the StreamBuffer to the Encoder::encoder() function. As the StreamBuffer
contains the source FrameBuffer and the destination Span, drop them from
the function arguments and access them directly from the StreamBuffer.
