Fix taint issue in Template/Provider.pm

I wrote a trivial patch to fix the taint issue reported in Template/Provider.pm
and which is filling the web server error log.

@fche: could you please attach this patch upstream on
https://github.com/abw/Template2/issues/258 (I don't have nor want a github
account). Thanks! :)
