coccicheck: make transformation for strbuf_addf(sb, "...") more precise
We can replace strbuf_addf() calls that just add a simple string with
calls to strbuf_addstr() to make the intent clearer. We need to be
careful if that string contains printf format specifications like %%,
though, as a simple replacement would change the output.
Add checks to the semantic patch to make sure we only perform the
transformation if the second argument is a string constant (possibly
translated) that doesn't contain any percent signs.
