Override lintian warnings about upgrading from old versions

There are some really things which are imperative that we fix in case
someone were to upgrade from a really old version.  We want to keep
these fixes in the postinst maintainer scripts, even though lintian
complains about such old upgrades not being supported by Debian in
general.  We prefer the code being there, for the sake of the users.

* debian/mandos-client.lintian-overrides
  (maintainer-script-supports-ancient-package-version): New.
  debian/mandos.lintian-overrides
  (maintainer-script-supports-ancient-package-version): - '' -
