    runtime: use correct types in __go_ptrace shim
    
    Make the types of the addr and data arguments in the __go_ptrace shim
    match the types declared in Go and the types declared by the C ptrace
    function, i.e., void*. This avoids a warning about an implicit
    int-to-pointer cast on some platforms.
