package/wireshark: security bump to version 3.2.4

Fix CVE-2020-13164: In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and
2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in
epan/dissectors/packet-nfs.c by preventing excessive recursion, such as
for a cycle in the directory graph on a filesystem.
