Upstream changed deb-pkg, and it no longer spits out a debian.tar.gz
archive. Take the debian folder generated by deb-pkg instead.

A second change is required because upstream now sets the target package
architecture as well, but dpkg-gencontrol will not like this in a cross
environment (host != package arch). Trick it.
