Extend signal testing framework to allow the definition of a custom per test initialization function to be run at the end of the common test_init after test setup phase has completed and before test-run routine.
This custom per-test initialization function also enables the test writer to decide on its own when forcibly skip the test itself using standard KSFT mechanism.
