Prepare for migrating to libburnia

As Thomas Schmitt suggested in KDEBUG-367639 adapting to cdrskin/xorriso
because cdrkit/wodim and dvd+rw-tools/growisofs are both dead projects,
as Kevin Kofler described, only Linux distributions packages patch them for
fixing BUG...

So it is the time to migrate to cdrskin/xorriso, please give me more code
review and help, thanks a lot!
