HHH-19444 SQLiteDialect - Fix ViolatedConstraintNameExtractor

See sqlite/sqlite@f9c8ce3
> Standardize the error messages generated by constraint failures to a format of "$TYPE constraint failed: $DETAIL".

Also in case [extended result codes](http://sqlite.org/c3ref/extended_result_codes.html) are activated, we need the `& 0xFF`.

And as there seems to be no way to tell `extractUsingTemplate` that there is no `templateEnd`, the linefeed is used...

See [original](https://github.com/gwenn/sqlite-dialect/blob/c87223460e3335ff4f041e012bd0d22df99fa2af/src/main/java/org/sqlite/hibernate/dialect/SQLiteDialect.java#L244-L253) code and associated [test](https://github.com/gwenn/sqlite-dialect/blob/c87223460e3335ff4f041e012bd0d22df99fa2af/src/test/java/org/hibernate/tutorial/annotations/AnnotationsIllustrationTest.java#L95-L105) for reference.
