selftest: af_unix: Add test for SO_INQ.

Let's add a simple test to check the basic functionality of SO_INQ.

The test does the following:

  1. Create socketpair in self->fd[]
  2. Enable SO_INQ
  3. Send data via self->fd[0]
  4. Receive data from self->fd[1]
  5. Compare the SCM_INQ cmsg with ioctl(SIOCINQ)
