UBUNTU: [Packaging] debian/rules: Drop NOKERNLOG and PRINTSHAS env variables

The env variables NOKERNLOG and PRINTSHAS were introduced in 2007 for
some special case and to retain old behavior when generating the
changelog. That hasn't been used in ages and git-ubuntu-log doesn't
even support it anymore since 2016 so drop it all.
