This uses a plain filepath.Walk + addTarFile to create a tar file,
optionially compressing it with gzip.
Unfortunately go only has gzip compression support, not bzip2 or xz.
However, this is not a regression, as docker currently uses *no*
compression for TarFilter(). The only compression of tarfiles
currently happens in utils/tarsum.go, and that manually does gzip
compression.
