daemon-windows: unlink pidfile before stopping the service.

Browse Source 
When a OVS daemon is configured to run as a Windows service,
when the service is stopped by calling service_stop(), the
windows services manager does not give enough time to do
everything in the atexit handler. So call the exit handler
directly from service_stop().

Also add a test case for Windows services which checks for
the termination of the service by looking at pidfile cleaned
by the exit handler.
