Bug#737632: autopkgtest: adt-run builds packages differently to the buildd

Hey Stuart,

This has been a source of quite a lot of errors recently indeed; I
haven't yet seen one that was due to not cleaning the package (I only
use it with already clean built trees or already built trees).

However, dpkg-buildpackage also defines env vars like
$DEB_HOST_MULTIARCH these days, which some packages use but don't
define. Granted, this is a bug in debian/rules and we have fixed a
number of them, but these days I really consider dpkg-buildpackage as
the primary interface to building binaries.

Therefore I fully agree to replacing "debian/rules build" with
"dpkg-buildpackage -us -uc -b", to do the same thing as our buildds.
Ian, what do you think about that?

Thanks,

Martin
