xdiff users: use designated initializers for out_line

Browse Source 
Amend the code added in 611e42a598 (xdiff: provide a separate emit
callback for hunks, 2018-11-02) to be more readable by using
designated initializers.

This changes "priv" in rerere.c to be initialized to NULL as we did in
merge-tree.c. That's not needed as we'll only use it if the callback
is defined, but being consistent here is better and less verbose.
