kunit: tool: Do not error on tests without test plans
The (K)TAP spec encourages test output to begin with a 'test plan': a count of the number of tests being run of the form: 1..n However, some test suites might not know the number of subtests in advance (for example, KUnit's parameterised tests use a generator function). In this case, it's not possible to print the test plan in advance. kunit_tool already parses test output which doesn't contain a plan, but reports an error. Since we want to use nested subtests with KUnit paramterised tests, remove this error.
