[SPARK-9725] [SQL] fix serialization of UTF8String across different JVM
The BYTE_ARRAY_OFFSET could be different in JVM with different
configurations (for example, different heap size, 24 if heap > 32G, otherwise
16), so offset of UTF8String is not portable, we should handler that during
serialization.
