9990-grml-networking.sh: display Grml info, update interfaces comment + operate on all net devices

* By displaying "Preconfiguring Grml networking" it's more
  explicit that we're running the 9990-grml-networking.sh code

* It's not the 23networking live-initramfs hook since quite some time,
  update the comment for generation of /etc/network/interfaces

* Support also new style network device names by iterating over
  /sys/class/net/* and skipping only the loopback interface
