[PATCH 1/1] license_image: Don't try to hard link license files

[paul@betafive.co.uk]

From: Paul Barker <paul@betafive.co.uk>

This change allows us to support the placement of WORKDIR and DEPLOY_DIR
on different devices. As the license files are typically small, the
increase in disk usage and build time should be negligible.
