  Config variable $nrconf{restart} is no longer accurate: it always
  restarts

  Fix Released

Bug description:
  [Impact]
  The normal configuration knob to change the behaviour of needrestart wrt restarting services vs asking the user vs just listing them doesn't work anymore
  on Noble due to the "Ubuntu mode" changes made during that cycle.

  [Test plan]

  echo '$nrconf{restart} = "l";' > /etc/needrestart/conf.d/listmode.conf
  apt reinstall libc6
  # The previous command should not have restarted any service.

  [ Where problems could occur ]

  If the patch is buggy, automatic restart could be disabled for all
  users. However, that use case is checked by the autopkgtests.

  [Original report]
  On Ubuntu 24.04:

  The conf /etc/needrestart/needrestart.conf contains:

  # Restart mode: (l)ist only, (i)nteractive or (a)utomatically.
  #
  # ATTENTION: If needrestart is configured to run in interactive mode but is run
  # non-interactive (i.e. unattended-upgrades) it will fallback to list only mode.
  #
  #$nrconf{restart} = 'i';

  Whether that variable is left at default (commented out) or defined
  with 'l' or 'i', services are still restarted.

  This config variable conflicts with the new behavior in [1].

  To reproduce: set "$nrconf{restart} = 'l'" run 'apt reinstall
  libssl3t64' on servers with Nginx, Redis, etc.

  Not sure if this setting should be respected, changed, or removed.
