git: update to v2.5.0

Update to git version v2.5.0.

* Upstream commit 5455ee0573a22bb793a7083d593ae1ace909cd4c (Merge branch
  'bc/object-id') changed API:

  for_each_ref() callback functions were taught to name the objects
  not with "unsigned char sha1[20]" but with "struct object_id".

  get_pathname() call sites return const char *)
