[SPARK-26936][SQL] Fix bug of insert overwrite local dir can not create temporary path in local staging directory

## What changes were proposed in this pull request?
Th environment of my cluster as follows:
```
OS:Linux version 2.6.32-220.7.1.el6.x86_64 (mockbuildc6b18n3.bsys.dev.centos.org) (gcc version 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC) ) #1 SMP Wed Mar 7 00:52:02 GMT 2012
Hadoop: 2.7.2
Spark: 2.3.0 or 3.0.0(master branch)
Hive: 1.2.1
```

My spark run on deploy mode yarn-client.

If I execute the SQL `insert overwrite local directory '/home/test/call_center/' select * from call_center`, a HiveException will appear as follows:
`Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: java.io.IOException: Mkdirs failed to create file:/home/xitong/hive/stagingdir_hive_2019-02-19_17-31-00_678_1816816774691551856-1/-ext-10000/_temporary/0/_temporary/attempt_20190219173233_0002_m_000000_3 (exists=false, cwd=file:/data10/yarn/nm-local-dir/usercache/xitong/appcache/application_1543893582405_6126857/container_e124_1543893582405_6126857_01_000011)
at org.apache.hadoop.hive.ql.io.HiveFileFormatUtils.getHiveRecordWriter(HiveFileFormatUtils.java:249)`
Current spark sql generate a local temporary path in local staging directory.The schema of local temporary path start with `file`, so the HiveException appears.
This PR change the local temporary path to HDFS temporary path, and use DistributedFileSystem instance copy the data from HDFS temporary path to local directory.
If Spark run on local deploy mode, 'insert overwrite local directory' works fine.
## How was this patch tested?

UT cannot support yarn-client mode.The test is in my product environment.

Closes apache#23841 from beliefer/fix-bug-of-insert-overwrite-local-dir.
