gl-renderer: conditionally call query_buffer while gl_renderer_attach

Browse Source 
While gl_renderer_attach, query_buffer should be call only if the
query_buffer function exists ie when has_bind_display is true.

v2:
 - Take into account Giulio's remark. Use has_bind_display viariable to test if
   EGL_WL_bind_wayland_display extension is supported.
