Bug description:
  Running apt-get purge linux-image-extra-4.3.0-2-generic linux-
  image-4.3.0-2-generic when newer kernel is present results in
  /etc/kernel/postrm.d/zz-zipl failing with the following error :

  E: Sub-process /usr/bin/dpkg returned an error code (1)

  
  When the hooks runs, /boot/vmlinuz and /boot/initrd.img are :

  caribou at caribou:~$ file /boot/vmlinuz /boot/initrd.img
  /boot/vmlinuz:    symbolic link to ./vmlinuz-4.3.0-2-generic
  /boot/initrd.img: broken symbolic link to ./initrd.img-4.3.0-2-generic

  The broken symlink to initrd.img-4.3.0-2-generic triggers the failure
