Summary:
When compiling RocksDB with Buck for ARM64, the linker complains about missing crc32 symbols that are defined in the crc32c_arm64.cc file. Since this file wasn't included in the build this is totally expected

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8168

Test Plan:
The following no longer fails to link rocksdb:
  buck build mode/mac-xcode //eden/fs/service:edenfs#macosx-arm64
