[autotest][PATCH] UBUNTU: SAUCE: fix missing setup on second run

[Krzysztof Kozlowski]

The autotest had nice idea that test setup can be executed only once on
a machine, till test version does not change.  If version stays the
same, autotest will not run test setup on next executions.

However this requirement/feature was not defined clear enough and some
tests:
1. Perform cleanup() which reverts the setup() (e.g. ubuntu_boot).
2. Set runtime configuration (e.g. initialize object's field in Python
   __init__()) during setup() and read it on each test (e.g.
   ubuntu_sysdig_smoke_test).

All of these cases fail.  Fix this by calling the test setup() every
time.
