init wayland support

The display server based on X or Wayland, is now a choice of different profile in Tizen 3.0.
Basically and consistently, two macros were used "with wayland" and "with x".
Below summarize the combination of the macros:

        | wayland |  x  | meaning
        |---------------------------
        |   0     |  1  | pure X11 platform(no wayland)
        |   1     |  0  | pure wayland platform (no X11)
        |   1     |  1  | wayland but X compatibility
        |   0     |  0  | no X and no wayland

This method unifies the meaning and usage. Deploy this method to app-svc package.
