dpkg-genchanges/genbuildinfo handle a binary-only upload by referencing
the previous source version textually (Source: pkg (prev),
Binary-Only: yes, Binary-Only-Changes) while distributing no source
files at all: pkh instead pulled the previous .dsc and its tarballs
into both documents whenever they sat next to the artifacts, re-uploading
the whole source on every binNMU.
Drop that redistribution (and include_dsc_artifacts with it), and emit
the missing Binary-Only: yes field, which the new differential test
against real dpkg-buildpackage -b caught. The binNMU case shares its
runner with the regular binary metadata differential; a unit test pins
the exclusion even with the previous artifacts present.
