Subject: i18n: Copy po/Makefile and remove-potcdate.plfrom debconf

These are from debconf.git a326240dd50487732d8546858994d48b45bf0b20.

There doesn't seem to be a common library for this kind of thing.  I'm
going to take debconf as a good example and nick the code.

Copyright: the debian/copyright file of debconf says it's
BSD-2-clause.  So add that, and copyright notices based on "git log"
(which does seem comprehensive).
