don't report vsnprintf(3) error as bug
strbuf_addf() has been reporting a negative return value of vsnprintf(3)
as a bug since f141bd804d (Handle broken vsnprintf implementations in
strbuf, 2007-11-13). Other functions copied that behavior:
7b03c89ebd (add xsnprintf helper function, 2015-09-24)
5ef264dbdb (strbuf.c: add `strbuf_insertf()` and `strbuf_vinsertf()`, 2019-02-25)
8d25663d70 (mem-pool: add mem_pool_strfmt(), 2024-02-25)
However, vsnprintf(3) can legitimately return a negative value if the
formatted output would be longer than INT_MAX. Stop accusing it of
being broken and just report the fact that formatting failed.
