- Fixed typo in function call for addBootLive
  It does not receive a parameter
- Add check for EFI fat image on iso media in makeIsoEFIBootable
  If the EFI fat image already exists don't recreate it. When building
  product media the image is provided by the installation-images-*
  package thus no need to create the same thing again. Also add
  a loginfo entry in this case
- Make sure package providing 'ip' command is installed in
  all boot image descriptions because the code using the obsolete
  ifconfig tool has been replaced by using the 'ip' command
- Make sure package providing 'fuser' command is installed in
  all boot image descriptions
- Make sure 'ip' and 'fuser' commands also exists for the
  boot descriptions for s390/ppc and arm architectures
- Fixed getNicNames in kiwi boot code (bnc #867148)
  * The function should ignore the loopback nic 'lo'
  * The network code should not deal with any fixed interface
    name like 'eth0'
