Corrected jinja template with tool Support works with PR llama.cpp/pull/15186

I have added tool support to llama.cpp [here](https://github.com/ggml-org/llama.cpp/pull/15186)
But parsing had issue with Zai's provided Jinja template.
I have added corrected template here.

+You may call one or more functions to assist with the user query.

+You are provided with function signatures within <tools></tools> XML tags:

+
+For each function call, output the function name and arguments within the following XML format:
