Previously we were leaving temporary directories behind. While the
QEMUMachine does make efforts to clean up after itself the directory
belongs to the calling function. We use TemporaryDirectory to wrap
this although we explicitly clear the reference in tearDown() as it
doesn't get cleaned up otherwise.

Double-checking that you really meant "avo" or if your fingers forgot to

It didn't introduce the problem in patch 2, it just moved it. The
mkdtemp() was never cleaned up before.
