ls-tree: remove commented-out code

Remove code added in f35a6d3 (Teach core object handling functions
about gitlinks, 2007-04-09), later patched in 7d0b18a (Add output
flushing before fork(), 2008-08-04), and then finally ending up in its
current form in d3bee16 (tree.c: allow read_tree_recursive() to
traverse gitlink entries, 2009-01-25). All while being commented-out!
