Subject: Add hard link support to gensquashfs and tar2sqfs

In libtar, set a special flag if the header is actually a hard link.

In tar2sqfs, create a hard link node and skip the rest for hard links.
Also refues to set the root attributes from a hard link, it may refere
to a node that we have missed earlier, there is nothing else that we
can do here.

In fstree_from_file, add a "link" command for adding hard links.
