[tools 3/3] testbot/LibvirtTool: Avoid a race between shutdown.exe and TestAgentd.

[Francois Gouget]

"shutdown.exe /p" waits for no process which may give it a slight edge
in not getting stuck; but it also does not wait for TestAgentd to reply
to the Run() RPC.
"shutdown.exe /s" does not seem to have this problem (and supports /t if
need be).
