added the function name to message in a couple of rules

[parsiya]

I thought having the function name in the message will help with triage either manually or using the message as a filter.

If this is something you want to incorporate, the decision is how you want the message to look like (e.g., where does the function name appear in the message). I am open to the location so it's clearer to users.

If this useful, I can go ahead and work on some of the other rules that have a similar structure.

Thank you for the PR! It's a nice idea and I didn't know that it was possible with Semgrep. I have to check how this change impacts SARIF Explorer and similar tools to make sure it doesn't break them. I'll get back to you after the holidays, during which I'll finally be AFK for some time. Cheers!
