tree-diff: diff_tree() should now be static

Browse Source 
We reworked all its users to use the functionality through
diff_tree_sha1 variant in recent patches (see "tree-diff: allow
diff_tree_sha1 to accept NULL sha1" and what comes next).

diff_tree() is now not used outside tree-diff.c - make it static.
