PTREL-546:disable ecore-x in the X-Free enviroment

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 ecore package.

The gl implementation in mesa, will bring glX directly, and triggle the X
 dependency, so pkgconfig(gl) will also trigle X dependency, also clean this
 in !{with x} condition.
