Add some code to automatically exit the kernel test

I occasionally test libcap against a custom kernel using QEMU.
Now I have a simple exit binary for exiting with status.

From the top level, one can use:

  make ktest

However, for more control:

  cd kdebug
  make test

If you want to look around after the tests run:

  make shell

Exit the shell & QEMU with ctrl-D (or exit).
