docs: Fix __builtin_object_size example [PR121581]
This example used to work (with C) in GCC 14 before the
warning for different pointer types without a cast was changed
to an error.
The fix is to make the q variable `int*` rather than the current `char*`.
This also fixes the example for C++ too.
Pushed as obvious after doing a `make html`.
