builddeb: Change architecture detection fallback to use dpkg-architecture

We currently use dpkg --print-architecture, which reports the architecture of the build machine. We can make a better guess than this by asking dpkg-architecture what the host architecture, i.e. the default architecture for building packages, is. This is sensitive to environment variables such as CC and DEB_HOST_ARCH, which should already be set in a cross-build environment.
