busybox: patch CVE-2024-58251

Pick patch applied by Debian [1].

I did not find any reference on busybox mailing list that this patch was
submitted. Submitting patch for someone else would be inappropriate,
and busybox is currently known to be very inactive, hence the unwanted
Pending Upstream-Status status.
Also note that the related busybox bugreport [2] is currently not
public, so it is possible that it was submitted there.
