btrfs-progs: move crc32c implementation to crypto/

With the introduction of xxhash64 to btrfs-progs we created a crypto/
directory for all the hashes used in btrfs (although no
cryptographically secure hash is there yet).

Move the crc32c implementation from kernel-lib/ to crypto/ as well so we
have all hashes consolidated.
