Error in setup-storage in FAI 4.1

[Thomas Neumann]

Hello Andreas

Please try this patch against an unmodified 'fai-setup-storage_4.2_all.deb' and 
install libcapture-tiny-perl. You can also remove liblinux-lvm-perl if you 
want.

This patch is a bit larger then actually necessary since I modified the debug 
output a bit and added 2 helper functions 'update_devicetree()' and 
'execute()'. These helpers are not mandatory but it should be seen as an 
investment for the future.

@LVM2 2.02.88 or below: The patched setup-storage checks for ancient versions 
but it simply tells you to update. 


Using your config as a testcase I got:
