    gdk/win32: remove extra allocation for \r removal
    
    Although I can't find explicit documentation for clipboard pointer, it
    seems to be possible to modify clibpoard memory without side-effects.
    
    According to MSDN,
    http://msdn.microsoft.com/en-us/library/windows/desktop/aa366596%28v=vs.85%29.aspx
    
    "The global and local functions are supported for porting from 16-bit
    code, or for maintaining source code compatibility with 16-bit
    Windows. Starting with 32-bit Windows, the global and local functions
    are implemented as wrapper functions that call the corresponding heap
    functions using a handle to the process's default heap."
    
    "Memory objects allocated by GlobalAlloc and LocalAlloc are in private,
    committed pages with read/write access that cannot be accessed by other
    processes. Memory allocated by using GlobalAlloc with GMEM_DDESHARE is
    not actually shared globally as it is in 16-bit Windows. This value has
    no effect and is available only for compatibility. "
