Remove expectedFailureWindows decorator.

expectedFailureWindows is equivalent to using the general
expectedFailureAll decorator with oslist="windows". Additionally,
by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without
arguments. Once all decorators are always called with arguments,
and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler
