[libgit2-glib] Fix user_data parameter in ggit_diff_blob_to_buffer()

[Christian Hergert <chergert src gnome org>]

commit 290f483222bc9805474f344d094358dd6ab052af

    Fix user_data parameter in ggit_diff_blob_to_buffer()
    
    gpointer is already a (void *), so the extra * only causes type warnings
    with the compiler. No ABI break necessary.
