diff: use add_diff_options() in diff_opt_parse()

Prepare the removal of the parseopts member of struct diff_options by using the API function add_diff_options() instead of accessing it directly to get the command line option definitions. Building the copy by concatenating with an empty option array is slightly awkward, but simpler than a non-concat version of add_diff_options() would be to use in places that need concatenation.
