[yocto] partitions resizing on the fly

I managed this issue redefining this script in my custom layer (rocko
branch):

    scripts/lib/wic/canned-wks/mkefidisk.wks

and setting a bigger size for the root partition (80GB in my case):

    part / --source rootfs --ondisk sda --fstype=ext4 --label platform
--align 1024 --use-uuid --*size 80000*

Its not very nice, I know. But yocto can't know the real size of your root
device until writing the final image.

I don't know if this is the best way to fix this  but it works.
