[PATCH v9 9/9] cocci: allow padding with `strbuf_addf()`

A convenient way to pad strings is to use something like `strbuf_addf(&buf, "%20s", "Hello, world!")`.

However, the Coccinelle rule that forbids a format `"%s"` with a constant string argument cast too wide a net, and also forbade such padding.

The original rule was introduced by commit:
