[PATCH 3/3] Rename git-diff-tree-helper to git-diff-helper (part 2).

It used to be that diff-tree needed helper support to parse its
raw output to generate diffs, but these days git-diff-* family
produces the same output and the helper is not tied to diff-tree
anymore.  Drop "tree" from its name.

This follows the "rename only" commit to adjust the contents of
the files involved.
