Squelch -Wformat-nonliteral in pcap_vasprintf().
On FreeBSD 13.1/AArch64 with Clang 13.0.0 "make asprintf.o" produced two
warnings:
./missing/asprintf.c:64:36: warning: format string is not a string
literal [-Wformat-nonliteral]
len = vsnprintf(&buf, sizeof buf, format, args);
^~~~~~
./missing/asprintf.c:75:33: warning: format string is not a string
literal [-Wformat-nonliteral]
ret = vsnprintf(str, str_size, format, args);
^~~~~~
Add printf()-related attributes to the prototype, as is already done for
pcap_asprintf().
