[SPARK-4908][SQL] Prevent multiple concurrent hive native commands

This is just a quick fix that locks when calling `runHive`.  If we can find a way to avoid the error without a global lock that would be better.

[SPARK-4975][SQL] Fix HiveInspectorSuite test failure

HiveInspectorSuite test failure：
[info] - wrap / unwrap null, constant null and writables *** FAILED *** (21 milliseconds)
[info] 1 did not equal 0 (HiveInspectorSuite.scala:136)
this is because the origin date(is 3914-10-23) not equals the date returned by ```unwrap```(is 3914-10-22).

Setting TimeZone and Locale fix this.
Another minor change here is rename ```def checkValues(v1: Any, v2: Any): Unit```  to  ```def checkValue(v1: Any, v2: Any): Unit ``` to make the code more clear
