[SPARK-22516][SQL] Bump up Univocity version to 2.5.9

## What changes were proposed in this pull request?

There was a bug in Univocity Parser that causes the issue in SPARK-22516. This was fixed by upgrading from 2.5.4 to 2.5.9 version of the library :

**Executing**
```
spark.read.option("header","true").option("inferSchema", "true").option("multiLine", "true").option("comment", "g").csv("test_file_without_eof_char.csv").show()
```
**Before**
```
ERROR Executor: Exception in task 0.0 in stage 6.0 (TID 6)
com.univocity.parsers.common.TextParsingException: java.lang.IllegalArgumentException - Unable to skip 1 lines from line 2. End of input reached
...
Internal state when error was thrown: line=3, column=0, record=2, charIndex=31
	at com.univocity.parsers.common.AbstractParser.handleException(AbstractParser.java:339)
	at com.univocity.parsers.common.AbstractParser.parseNext(AbstractParser.java:475)
	at org.apache.spark.sql.execution.datasources.csv.UnivocityParser$$anon$1.next(UnivocityParser.scala:281)
	at scala.collection.Iterator$$anon$11.next(Iterator.scala:409)
```
**After**
```
+-------+-------+
|column1|column2|
+-------+-------+
|    abc|    def|
+-------+-------+
```

## How was this patch tested?
The already existing `CSVSuite.commented lines in CSV data` test was extended to parse the file also in multiline mode. The test input file was modified to also include a comment in the last line.
