timer.windows: Fix test problems for Windows.

* Filter some testcases that need to change clocksource out
  for Windows.
* Fix parameter error: operation should be stress_type in
  configuration file.
* Windows OS use localtime as hardware time, while Unix is UTC.
  So they should have different checking way.
  TimeZone time in windows should compare with 'UTC time' on host
  for different clock type in XML.
