[SPARK-20978][SQL] Bump up Univocity version to 2.5.4
## What changes were proposed in this pull request?
There was a bug in Univocity Parser that causes the issue in SPARK-20978.
This was fixed as below:
```scala
val df = spark.read.schema("a string, b string, unparsed
string").option("columnNameOfCorruptRecord", "unparsed").csv(Seq("a").toDS())
df.show()
```
**Before**
```
java.lang.NullPointerException

```
**After**
```
+---+++
| a| b|unparsed|
+---+++
| a|null| a|
+---+++
```
It was fixed in 2.5.0 and 2.5.4 was released. I guess it'd be safe to
upgrade this.
## How was this patch tested?
Unit test added in `CSVSuite.scala`.
