Use snprintf instead of sprintf for get_ssl_library_version

Browse Source 
This is avoid a warning/error (when using -Werror) under current macOS
of sprintf:

   __deprecated_msg("This function is provided for compatibility
   reasons only.  Due to security concerns inherent in the design
   of sprintf(3), it is highly recommended that you use snprintf(3)
   instead.")
