HIVE-4516 Fix concurrency bug in
serde/src/java/org/apache/hadoop/hive/serde2/io/TimestampWritable.java

scenario (as found in AmpLab Shark). A static SimpleDateFormat (not
ThreadSafe) is used by TimestampWritable in CTAS DDL statements where it
manifests as data corruption when used in a concurrent environment.
