Add uncompressed and xz control.tar deb member support
These are currently not accepted by the Debian archive, but are
supported since dpkg 1.17.6, and they do not incur any additional
dependency from the host system. This is mostly for completeness'
sake, as Debian base packages with uncompressed or xz control.tar
members are probably not going to be used at all.
