[SPARK-14423][YARN] Avoid same name files added to distributed cache again
## What changes were proposed in this pull request?
In the current implementation of assembly-free spark deployment, jars under `assembly/target/scala-xxx/jars` will be uploaded to distributed cache by default, there's a chance these jars' name will be conflicted with name of jars specified in `--jars`, this will introduce exception when starting application:
```
client token: N/A
diagnostics: Application application_1459907402325_0004 failed 2 times due to AM Container for appattempt_1459907402325_0004_000002 exited with exitCode: -1000
For more detailed output, check application tracking page:http://hw12100.local:8088/proxy/application_1459907402325_0004/Then, click on links to logs of each attempt.

```
So here by checking the name of file to avoid same name files uploaded again.
## How was this patch tested?
Unit test and manual integrated test is done locally.
