Do not require vsnprintf().
The check for vsnprintf() has been in the configure script since commit
8cb054c in 2000, and the only actual use of the function was in the
"#ifndef HAVE_SNPRINTF" block in missing/snprintf.c until commit 1ed63b5
in 2019. Since then tcpdump does not require vsnprintf() in any way.
(cherry picked from commit a69de5a4d94baabdceb22a174b116b6e45ed72b9)
