Fix: libfstree: actually use a full 32 bit hard link counter
The squashfs on-disk format uses 32 bit link counters, but the fstree used 16 bit ones. Because the link count also includes child nodes, this artificially limited the number of entries in a directory to ~64k files. This patch removes the limit by switching libfstree to 32 bit counters.
