man: fix "no-auto-default" state dir in NetworkManager.conf manual

Quote from `man NetworkManager.conf`:

  When the default wired connection is deleted or saved to a new
  persistent connection by a plugin, the device is added to a list in the
  file /run/NetworkManager/no-auto-default.state to prevent creating
  the default connection for that device again.

"/run" is obviously wrong. Fix it.
