[Tizen] Use strdup instead of SWIGRegisterStringCallback_NDalic called

Let we use SWIG_csharp_string_callback as strdup, instead of SWIGRegisterStringCallback_NDalic registered callback.

duplicated string's reference will be released automatically at C# managed memory side. So strdup has
no problem for natural cases.
