tpl_wayland_egl: Modify creating event queue for multi-threaded usage

In multi-threaded wayland, below is guided on creating own event queue:
  Create a wl_interface object with a specified event queue, instead of
  creating an object and then changing it’s queue.

This patch applies this guideline on where creating own event queue.
