Adjust test. You're not supposed to change errno in a signal handler and
count on it being observable in the normal program flow after the signal
handler returns. Such code would break code that sets errno to 0 and
looks at its value later. With the recent futex(2) changes this particular
aspect of the test no longer passed.
