kqueue tests: Simplify the test runner

Just invoke the test program directly instead of trying to convert its
output to TAP format.  The test suite is all or nothing; there's no way
to enumerate individual test cases, so there's no advantage in trying to
massage its output, and doing so throws away information that's useful
when diagnosing test failures.
