Moved the test out of test/include. The new test is an integration test under test/integration/src/unistd that forks children which exit, are signalled, stop and continue, and decodes the statuses the kernel produces. WIFSIGNALED now evaluates its argument once. I compiled the test but have not run it through the CMake integration target.
