Andrei Gudkov 00a3f9c60a migration/calc-dirty-rate: replaced CRC32 with xxHash ...

This significantly reduces overhead of dirty page
rate calculation in sampling mode.
Tested using 32GiB VM on E5-2690 CPU.

With CRC32:
total_pages=8388608 sampled_pages=16384 millis=71

With xxHash:
total_pages=8388608 sampled_pages=16384 millis=14
