tools/mm/page_owner_sort: fix timestamp comparison for stable sorting
The ternary operator in compare_ts() returns 1 when timestamps are equal,
causing unstable sorting behavior. Replace with explicit three-way
comparison that returns 0 for equal timestamps, ensuring stable qsort
ordering and consistent output.
