Allow zero size with non-null buf in *asnprintf.
* libc/stdio/asnprintf.c (_asnprintf_r, asnprintf): Avoid free'ing
user's buf.
* libc/stdio/asniprintf.c (_asniprintf_r, asniprintf): Likewise.
* libc/stdio/vasniprintf.c (_vasniprintf_r): Likewise.
* libc/stdio/vasnprintf.c (_vasnprintf_r): Likewise.
