test-lfs: allow the test server to be killed on Windows

Apparently '$!' doesn't return a Win32 PID, so the process was never killed, and
the next run was screwed up.  Oddly, without the explicit killdaemons.py at the
end, the test seems to hang.  This spawning is just sad, so I limited it to
Windows.
