smoketest: refactor setUp() for all interface based testcases

It does not make sense (at all!) to re-initialize the entire class with every
call to setUp(). We neither change the enabled/disabled tastcases dynamically,
not do we adjust the testinterfaces during a run.

Remove the runtime overhead and place one-time init calls into setUpClass()
instead.

(cherry picked from commit b48890396dcff074d1e9336ca1db9d3eafe2a12f)
