".tar.bz2" is just added to package name and version,
it is not really derived from the package file


$ grep -H  "tar.bz2" package_db.cc
package_db.cc:      pkgm.name + "-" + 
std::string(pkgm.installed.Canonical_version()) + ".tar.bz2 " +


When we moved from bz2 to xz, that shortcut was not changed.
