libio: remove ostream_append_sparse and fallback implementation

Instead of a separate append-sparse function, simply accept NULL
as an input for append. For both Unix and Win32, a fallback needs
to be implemented. For XFRM, we can just memset the input buffer
to zero, same for the libsquashfs data writer.
