test/setup: Add initital tests for setup.sh

This is first commit from the series introducing funcrional tests
for setup.sh. Issues like #1689, #1691 showed that major changes
to setup.sh may result in quite unexpected behavior. thus to avoid
any regression, we should make sure  the core of its functionality
is properly tested.

For now, only Linux systems are supported tests-wise.

The tests are explicitly run after all OCSSD are put into PCI_BLOCKED
to make sure they won't be picked up by the tests.
