Make wineserver exit immediately

After cl.exe exited, wineserver waits for 3 seconds to terminate.
Actually this is not necessary. So, let's make wineserver terminate
immediately after cl.exe has finished.

This patch makes each task of cl.exe 3 seconds faster.
I've confirmed that we can compile chrome with this change.
