wine data downloading is defect

[kno10]

Because of the wine_qual data, it won't download the wine data automatically

wine_qual*.csv mlpack.org/datasets/wine_qual.tar.gz
wine*.csv mlpack.org/datasets/wine.tar.gz

... because the glob matches the wine_qual data already. Remove the star?

Nice catch, thanks; #121 resolved the issue.
