[SPARK-17796][SQL] Support wildcard character in filename for LOAD DATA LOCAL INPATH

## What changes were proposed in this pull request?

Currently, Spark 2.0 raises an `input path does not exist` AnalysisException if the file name contains '*'. It is misleading since it occurs when there exist some matched files. Also, it was a supported feature in Spark 1.6.2. This PR aims to support wildcard characters in filename for `LOAD DATA LOCAL INPATH` SQL command like Spark 1.6.2.

**Reported Error Scenario**
```scala
scala> sql("CREATE TABLE t(a string)")
res0: org.apache.spark.sql.DataFrame = []

scala> sql("LOAD DATA LOCAL INPATH '/tmp/x*' INTO TABLE t")
org.apache.spark.sql.AnalysisException: LOAD DATA input path does not exist: /tmp/x*;
```

## How was this patch tested?

Pass the Jenkins test with a new test case.
