Add "--debbuildopts -b" to "pbuilder build" command line to stop pbuilder from creating a source package. The .changes would otherwise contain references to that new source package instead of the one we passed to pbuilder. The checksums for the two source packages would be different so the .changes file would not match the source package that treepkg produces.
