testbot/LibvirtTool: Reduce the Windows boot delay on live snapshots.

Reducing the boot delay helps ensure there will be enough time for
Windows to complete the reboot before the task times out, which may
allow the TestBot to retrieve the report/logs/diagnostic information.
Note that on 64-bit Windows this requires a 64-bit TestAgentd in order
to be able to run bcdedit.exe.
Also this only works on recent versions of Windows which is okay since a
failure to change the boot delay will not prevent the tests from
running.
