Lukas Czerner 83ef157def common: Check fs consistency on TEST_DEV only when needed
Currently we're checking file system consistency on TEST_DEV after every
successful test run even though the TEST_DEV might not even be used in
that test.

Fix it by introducing _require_test to for the test ti indicate that
it's about to use TEST_DEV.

Also add _require_test to the new script so that this requirement is a
default.
