selftests: ktap_helpers: Fix uninitialized variable
__ktap_test() may be called without the optional third argument which is an issue for scripts using `set -u` to detect uninitialized variables and potential bugs. Fix this optional "directive" argument by either using the third argument or an empty string. This is required for the next commit to properly test script execution control.
