vorbisgain FTBFS fix

vorbisgain-0.36-12.fc20 fails to build if "-Werror=format-security" flag is used.

I am working on a proposal to enable "-Werror=format-security" for all packages. For more details, please see https://fedorahosted.org/fesco/ticket/1185 URL.

I have attached a trivial patch to fix this problem. Please review and apply.
