Move from consolekit to logind

This bug was fixed in the package openssh - 1:6.9p1-3

---------------
openssh (1:6.9p1-3) unstable; urgency=medium

  * ssh_config(5): Fix markup errors in description of GSSAPITrustDns
    (closes: #799271).
  * Fix dh_install and dh_fixperms overrides to work properly with an
    architecture-independent-only build (closes: #806090).
  * Do much less work in architecture-independent-only builds.
  * Drop ConsoleKit session registration patch; it was only ever enabled for
    Ubuntu, which no longer needs it (LP: #1334916, #1502045).

With the latest upload, Debian has dropped all support for consolekit on Linux architectures:

consolekit (0.4.6-6.1) unstable; urgency=medium

  * Non-maintainer upload.
  * Mark packages as kfreebsd-any hurd-any. On Linux, the consolekit package
    is actively harmful and should no longer be installed. See #888892

The logical next step is to blacklist consolekit in Ubuntu and remove it from the archive for bionic.

However, lxdm has a dependency on libck-connector0, so we can't remove it without breaking this package.

I am therefore uploading it to drop the dependency.

mate-power-manager and polkit-qt-1 still have consolekit as a non-default alternative dependency. They should be updated to drop this reference, so that all users will be migrated to libpam-systemd on upgrade if they haven't been already.

This will not block consolekit's removal from the bionic archive.

This bug was fixed in the package lxdm - 0.5.3-2ubuntu1

---------------
lxdm (0.5.3-2ubuntu1) bionic; urgency=medium

  * Drop build dependency on the obsolete libck-connector-dev.

This bug was fixed in the package lxsession - 0.5.3-2ubuntu1

---------------
lxsession (0.5.3-2ubuntu1) bionic; urgency=medium

  * Drop the dependency on consolekit in favor of the systemd replacements
    (LP: #1502045).
