[tools 2/3] testbot/LibvirtTool: Fix detecting the 'high privileges' TestAgentd.

[Francois Gouget]

The SetTime() leeway should be 0 otherwise it may skip actually setting
the time and thus not fail if privileges are insufficient.

The 'high privileges' detection is usually only done once and before the 
VM's time has been updated. Since this normally happens a lot more than 
30 seconds after the live snapshot has been created this is normally not 
an issue. It would likely fail for powered-off snapshots however since 
they update their time on boot.
