Stop writing logs to %ProgramData%\Chromoting\debug.log (Windows only).

%ProgramData% is read-only for processes running at low integrity level. since the host is now running at low integrity level and logs are written to ETW, this CL quits using debug.log altogether. See http://code.google.com/p/sawbuck/wiki/HowToCaptureLogsOffline for an example how logs can be collected via ETW infrastructure. The Chromoting provider's guid is "{2db51ca1-4fd8-4b88-b5a2-fb8606b66b02}".
