[SPARK-19990][SQL][TEST-MAVEN] create a temp file for file in test.jar's resource when run mvn test accross different modules

## What changes were proposed in this pull request?

After we have merged the `HiveDDLSuite` and `DDLSuite` in [SPARK-19235](https://issues.apache.org/jira/browse/SPARK-19235), we have two subclasses of `DDLSuite`, that is `HiveCatalogedDDLSuite` and `InMemoryCatalogDDLSuite`.

While `DDLSuite` is in `sql/core module`, and `HiveCatalogedDDLSuite` is in `sql/hive module`, if we mvn test
`HiveCatalogedDDLSuite`, it will run the test in its parent class `DDLSuite`, this will cause some test case failed which will get and use the test file path in `sql/core module` 's `resource`.

Because the test file path getted will start with 'jar:' like "jar:file:/home/jenkins/workspace/spark-master-test-maven-hadoop-2.6/sql/core/target/spark-sql_2.11-2.2.0-SNAPSHOT-tests.jar!/test-data/cars.csv", which will failed when new Path() in datasource.scala

This PR fix this by copy file from resource to  a temp dir.
