[PATCH 1/6] Acceptance Tests: add standard clean up at test tearDown()

[Willian Rampazzo <willianr@redhat.com>]

From: Cleber Rosa <crosa@redhat.com>

The avocado.Test class, used as the basis of the avocado_qemu.Test
class, performs a clean of temporary directories up as part of its own
tearDown() implementation.

But the avocado_qemu.Test class is currently missing the same clean
up, as it implemented its own tearDown() method without resorting to
the upper class behavior.

This brings avocado_qemu.Test behavior in sync with the standard
avocado.Test behavior and prevents temporary directories from
cluttering the test results directory (unless instructed to do so with
Avocado's "--keep-tmp" option).
