Since 6b13bc3232 (xdiff: simplify comparison, 2021-11-17), we do not call xdl_recmatch() from xdiffi.c's recs_match(), so we no longer need the "flags" parameter. That in turn lets us drop the flags parameters from the group-slide functions which call it.
There's no functional change here; it's just making these functions a little simpler.
