merge-recursive.c: use string_list_sort instead of qsortnd/qsort-in-merge-recursive
Merge-recursive sorts a string list using a raw qsort(), where it feeds the "items" from one struct but the "nr" and size fields from another struct. This isn't a bug because one list is a copy of the other, but it's unnecessarily confusing (and also caused our recent QSORT() cleanups via coccinelle to miss this call site). Let's use string_list_sort() instead, which is more concise and harder to get wrong. Note that we need to adjust our comparison function, which gets fed only the strings now, not the string_list_items. That's OK because we don't use the "util" field as part of our sort.
