evas gl: make 9 patch work

Summary:
The 9 patch is using image_stretch_region_get, but GL did not override it.
So the 9 patch did not work for GL engine at all.

Test Plan:
Evas_Object*img = evas_object_image_filled_add(evas);
evas_object_image_file_set(img, "test.9.png", 0);
evas_object_show(img);
