[BoundsSafety] Unbreak AST/typedef-function-attrs-late-parsed-call.c test

The test broke because a new diagnostic from upstream started firing and
was mixed in with the AST dump.

The upstream diagnostic is from:

```
commit 576161c
Author: Aaron Ballman <[email protected]>
Date:   Fri Apr 25 08:21:41 2025 -0400

    [C] Warn on uninitialized const objects (llvm#137166)
```

The simplest solution is to surpress the new diagnostic.
