test-runner: Don't use killall

Browse Source 
killall doesn't wait for the iwd process to clean up, so using it is not
enough when cleaning up between tests.

Using killall -w also doesn't work since iwd is launched by the script.
By the time killall is invoked, the script process is also cleaned up.
So when iwd is killed via killall, nobody is there to reap the zombie
process (test-runner is running as init, but doesn't do this)

The easiest solution is to make the test script itself clean up any iwd
processes it launches.  This is what has been implemented in the
previous patch.
