lib/oeqa/runtime: remove some unnecessary checks from setUpModule

These checks are unnecessary.
setUpModule is run when a module is loaded and we
shouldn't run commands on the target here, (plus if
ssh doesn't work we error out in setup multiple times, instead
of skipping the real test, which might depend on test_ssh).
