    tdf#127069 sal: preserve gid of files in the unx osl_replaceFile()
    
    The w32 implementation preserves all attributes of the destination
    file, the unx one preserved none of them.
    
    Bring the unx osl_replaceFile() closer to the w32 by preserving the gid
    of the destination file as a start.
    
    [ No testcase, we support building on systems where the user is part of
    a single group only, and it's not possible to verify the effect of this
    change in such environments. ]
