To avoid AppArmor-related test failures when functional test are run from somewhere under /mnt, adjust the path to swtpm's state to use an AppArmor- supported path, such as /var/tmp, which is provided by the python function tempfile.TemporaryDirectory().
An update to swtpm's AppArmor profile is also being done to support /var/tmp.
