cogl-material: Fix some problems with flushing texture overrides

There were a few problems flushing texture overrides so that sliced
textures would not work:

* In _cogl_material_set_layer_texture it ignored the 'overriden'
  parameter and always set texture_overridden to FALSE.

* cogl_texture_get_gl_texture wasn't being called correctly in
  override_layer_texture_cb. It returns a gboolean to indicate the
  error status but this boolean was being assigned to gl_target.

* _cogl_material_layer_texture_equal did not take into account the
  override.

* _cogl_material_layer_get_texture_info did not return the overridden
  texture so it would always use the first texture slice.
