    Add a new program, dh_genbuildinfo, to generate a .buildinfo file after build
    
    This is a proof of concept. The functionality should probably be in a
    "dpkg-genbuildinfo" program instead, but we're putting it in debhelper
    for now to reduce the number of patched packages needed by the "Debian
    Reproducible Builds" effort.
    
    This wrapper is separate from gen-buildinfo, which it leverages on,
    because that one could realistically be merged into the dh-buildinfo
    package.
