  1. entry: convert hard link absolute paths to relative ones 

    When unpacking a docker image, some hard links may be pointing to, say,
/bin/gunzip. Those were failing the validate_inside_dst() check,
preventing to unpack the image.

Fix this by re-using the same logic as we are already using for actual
files, removing the leading '/' from the link target path.

We do this only if the absolute link is not an ancestor of the target
dir as we want to support this use case according to the existing
absolute_hardlink() test.
