[Reproducible-builds] buildinfo patch breaks .changes

[HW42]

Hi,

our dpkg patch [0] to add buildinfo files to dpkg has a small bug. The
problem is that Dpkg::Dist::Files.parse_filename [1] doesn't handle
buildinfo files correctly and sets the buildinfo identifier as arch.
Therefore the generates .changes contains something like:

  Architecture: amd64 all 20160613T013823z-ff7bd155

The attached patch fixes this and should be stashed into the buildinfo
patch.
