win-capture: Rename structs to avoid SDK conflict

Windows SDK 10.0.16299.0 defines these structures as part of winternl.h
but using different types and names. Unfortunately there's no macro to
detect the SDK version, so to avoid conflicting with newer / older SDKs
the OBS structs have been renamed.
