Autologin rework

* Passes through PAM (pam_systemd module) via login(1). This sets up
  systemd --user instance, which will create and listen on dbus session socket.

* login(1) is called (via agetty(8)) with -p option, keeping the environment
  pam_systemd configured for the user, most importantly
  DBUS_SESSION_BUS_ADDRESS.

* Thus dbus-launch call in /etc/X11/xinit/xinitrc is unnecessary.

* autologin.conf drop-in configured in the template unit (getty@.service)
  to make autologin work on all virtual consoles.
