image_signing: use sparse copying when creating the signed image

Browse Source 
This should speed up the copies significantly by using less disk
storage & I/O when the unpacked file is not sparse already.  This
option has been in cp for a long time, and works in Ubuntu Precise
(coreutils-8.13) & Trusty (coreutils-8.21).
