[PATCH 2/2] cruft-report: Prefer .xz files over .gz

[Emilio Pozuelo Monfort <pochu@debian.org>]

We are getting rid of .gz Packages and Sources, which are
already gone from experimental, and that causes the cruft
report to fail there. So look for the xz-compressed files
first, and fall-back to the gzip-compressed ones if the
former don't exist (e.g. for oldstable).
