Silence -Walloc-size-larger-than=byte-size 

One of the GCC14's optimization heuristic triggered here, suggesting
that the special value of len (size_t) could potentially be lesser than
the file's size (int64_t) but greater than "maximum object size" (set by
byte-size, PTRDIFF_MAX by default).

Use the same type as the file size it's compared to, and adjust the
sentinel value to spell INT64_MAX.
