[dev.boringcrypto] runtime/race: move TestRaceIssue5567 from sha1 to crc32

If we substitute a SHA1 implementation where the entirety of the
reading of the buffer is done in assembly (or C called from cgo),
then the race detector cannot observe the race.

Change to crc32 with a fake polynomial, in the hope that it will
always be handled by Go code, not optimized assembly or cgo calls.
