Disable the autologin text consoles (Closes: #5588).
Adapt doc accordingly to the kernel cmdline change.

It's probably still wrong, but at least a bit less outdated.
Drop console localization profile.d snippet.

We don't autologin the consoles anymore, so we don't need something this
complicated anymore. I could not bother myself to adapt and simplify it as:

 * It's broken on feature/wheezy (#5583) and I see little use in spending any
   time on this feature at this point.
 * Seriously, the intended users (debugging for developers or power-users) can
   as well `loadkeys' their preferred layout.
 * The removed snippet required tails-greeter to give the "amnesia" user the
   right to run "setupcon" as root.
