fetch-pack: use DEFINE_LIST_SORT

Build a static typed ref sorting function using DEFINE_LIST_SORT along
with a typed comparison function near its only two callers instead of
having an exported version that calls llist_mergesort().  This gets rid
of the next pointer accessor functions and their calling overhead at the
cost of a slightly increased object text size.
