[Qemu-block] [PATCH v8 4/6] iotests: Valgrind fails with nonexistent dir

From: Andrey Shinkevich
Subject: [Qemu-block] [PATCH v8 4/6] iotests: Valgrind fails with nonexistent directory
Date: Wed, 4 Sep 2019 12:11:22 +0300

The Valgrind uses the exported variable TMPDIR and fails if the
directory does not exist. Let us exclude such a test case from
being run under the Valgrind and notify the user of it.
