Evas GL: use texture for native surface in glx backend

Summary:
EVAS_NATIVE_SURFACE_EVASGL uses egl image, but egl image is
not supported in glx backend, so use texture instead.

Test Plan: Local tests on pc

Reviewers: jpeg

Subscribers: cedric, mer.kim, mythri, wonsik

Differential Revision: https://phab.enlightenment.org/D2174

jpeg: fixed casts
