Subject: [PATCH] tests: add prefixes to the bare mkdtemp calls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first step to debug a thing is to know what created the thing in
the first place. Add some prefixes so random tmpdir's have something
grep in the code.
