File _service:obs_scm:wireshark-0006-Move-tmp-to-var-tmp.patch of Package wireshark

From cb54210f7f02b07768cfbf49ae266d487f580e1b Mon Sep 17 00:00:00 2001
From: rpm-build <rpm-build>
Date: Thu, 29 Jun 2017 15:32:58 +0200
Subject: [PATCH] Move /tmp to /var/tmp

Fedora is using tmpfs which is limited by the size of RAM, thus we need
to use different directory on different filesystem.
