bitbake: fetch2: fix unpacking of deb packages
deb packages in modern Debian versions have the data tarball compressed
with xz rather than gzip, and thus explicitly extracting data.tar.gz
fails. Unfortunately ar doesn't support wildcards matching items to
extract, so we have to find out what the name of the file is first and
then extract it, relying on tar to figure out how to unpack it based on
the filename rather than doing it with pipes and making that
determination ourselves.
