Respect --without-chroot correctly

./configure --without-chroot will configure tcpdump with "no" as the
value of chroot directory and cause tcpdump to fail with:

tcpdump: Couldn't chroot/chdir to 'no': No such file or directory

This patch makes ./configure to avoid chroot directory when called with
--without-chroot.
