dd: work around Linux kernel CLOCK_MONOTONIC bug

Problem reported by Sick Pigs (bug#81269).
Ordinarily we’d say “fix the kernel or the hardware”,
but this bug seems widespread and unlikely to be fixed any time soon,
and the workaround is not a lot of trouble.
* src/dd.c (real_start_time): New static var.
(getrealxtime): New static function.
(print_xfer_stats): Use the max of elapsed monotonic and elapsed
real time.
