Fixed bug in BitmapFactory.decodeStream

Downloading images over a slow connection could result in errors and
null images.

The JavaInputStreamAdaptor::do_skip method was correctly called in a
loop (to handle the EOF case using read()), but the amount that was
skipped at each time was not decreased by the amount already skipped.
