hyukjinkwon 4a14dc0aff [SPARK-22269][BUILD] Run Java linter via SBT for Jenkins
## What changes were proposed in this pull request?

This PR proposes to check Java lint via SBT for Jenkins. It uses the SBT wrapper for checkstyle.

I manually tested. If we build the codes once, running this script takes 2 mins at maximum in my local:

Test codes:

```
Checkstyle failed at following occurrences:
[error] Checkstyle error found in /.../spark/core/src/test/java/test/org/apache/spark/JavaAPISuite.java:82: Line is longer than 100 characters (found 103).
[error] 1 issue(s) found in Checkstyle report: /.../spark/core/target/checkstyle-test-report.xml
[error] Checkstyle error found in /.../spark/sql/hive/src/test/java/org/apache/spark/sql/hive/JavaDataFrameSuite.java:84: Line is longer than 100 characters (found 115).
[error] 1 issue(s) found in Checkstyle report: /.../spark/sql/hive/target/checkstyle-test-report.xml
...
```

Main codes:

```
Checkstyle failed at following occurrences:
[error] Checkstyle error found in /.../spark/sql/core/src/main/java/org/apache/spark/sql/sources/v2/reader/InputPartition.java:39: Line is longer than 100 characters (found 104).
[error] Checkstyle error found in /.../spark/sql/core/src/main/java/org/apache/spark/sql/sources/v2/reader/InputPartitionReader.java:26: Line is longer than 100 characters (found 110).
[error] Checkstyle error found in /.../spark/sql/core/src/main/java/org/apache/spark/sql/sources/v2/reader/InputPartitionReader.java:30: Line is longer than 100 characters (found 104).
...
```

## How was this patch tested?

Manually tested. Jenkins build should test this.
