smoketest: T7858: make failfast main argument dynamic

When smoketest debugging is enabled (by creating the file
/tmp/vyos.smoketest.debug), all available smoketests will fail fast instead
of running to completion. This helps reduce test time when something is
broken or undergoing refactoring, as it avoids waiting for the full test suite
to finish.
