undefined symbol: wl_display_get_rgb_visual

[Benjamin Franzke]

The symbol isnt in wayland anylonger. egl_gallium is broken since Kristian
changed how visuals are emitted in wayland (commit 4bde293).

So either use egl_dri2 (export EGL_PLATFORM=egl_dri2) or the following
patch that i'll send to Kristian:
