tcpreplay: fix pcap detection with /usr/lib32 multilib

* use BPN, BP where useful
* use prefix instead of hardcoding /usr
* add patch to search also in lib32 subdir of --with-libpcap value
  to fix:
  checking for libpcap... configure: error: "Unable to find matching library for header file in TOPDIR/BUILD/work/raspberrypi4_64-oemllib32-linux-gnueabi/lib32-tcpreplay/4.4.4-r0/lib32-recipe-sysroot/usr"

+Subject: [PATCH] configure.ac: unify search dirs for pcap and add lib32
+
+* add lib32 because when building lib32-tcpreplay it's
+  impossible to set --with-libpcap so that it would find
+  both include files as well as the library in lib32 directory
+
+* maybe it would be beneficial to split --with-libpcap
+  into --with-libpcap-includedir --with-libpcap-libdir as this
+  already searches in the --with-libpcap value with and
+  without any "lib" prefix, but include files always expect
+  "include" dir there
+
+* most of this code was added in:
+  https://github.com/appneta/tcpreplay/commit/202b8e82f9fd3c84ce5804577caeb36a33baabe7#diff-49473dca262eeab3b4a43002adb08b4db31020d190caaad1594b47f1d5daa810R570
+
+* then search for
+  ${host_cpu} lib/${host_cpu} (without -${host_os} suffix)
+  and ${build_arch}-${host_os} lib/${build_arch}-${host_os}
+  was added, but only for search of dynamic library in:
+  https://github.com/appneta/tcpreplay/commit/c3d5236563985a99f8bb02c3f1bd6950e3929047
+
+* ${build_arch}-${host_os} lib/${build_arch}-${host_os}
+  was later replaced with:
+  lib/${MULTIARCH} ${MULTIARCH}
+  and it was added to static library search as well
+
+  but for dynamic library it was searching in reversed order:
+  ${MULTIARCH} lib/${MULTIARCH}
+  https://github.com/appneta/tcpreplay/commit/ed9e3a818bde04813144014561e62f018c9eb85f
+
+  I don't think this reversed order was intentional, just unify all 4 cases
+  to use the same directories in the same order
