debathena-kerberos-config upgrade left behind obsolete conffile

Something else is weird here, too, because the orig file I have is /etc/apparmor.d/usr.sbin.cupsd and not /etc/apparmor.d/usr.sbin.cups.

       So yeah - it looks like geofft's 1.7.1 accidentally replaced
       usr.sbin.cupsd.debathena with usr.sbin.cups.debathena
   debathena / trac-#325 / andersk  12:36  (Anders Kaseorg)
       It also left the /etc/apparmor.d/abstractions/kerberosclient diversion
       in place.
   debathena / trac-#325 / broder  12:36  (Evan Broder)
       Yeah, I can see how our packaging wouldn't be clever enough to deal
       with that case
   debathena / trac-#325 / broder  12:37  (Evan Broder)
       I...think...that what we want to do is
       (a) add an "else" clause for both of the ifneqs in the debian/rules that
       DEB_UNREMOVE_FILES's the files
       (b) Fix the typo'd filename
       (c) Add logic to the postinst to remove usr.sbin.cups.debathena if it
       exists

I moved this fix to production yesterday.
