windows: fix signature of GetFinalPathNameByHandle

The function name should be GetFinalPathNameByHandle, not
GetFinalPathNameByHandleW, and it should take types in windows, not in
syscall. This was merged so recently that I think we can just fix it up
here.

Updates golang/go#41686
Fixes CL 264577
