clutter-texture: Don't create a dummy texture

Browse source 
All of the pipelines used for ClutterTexture actors share a common
pipeline ancestor created with cogl_pipeline_copy. Previously this
ancestor had a dummy 1x1 texture attached to it so that it would end
up with the same state as the child pipelines that will render with a
texture. Cogl now has a mechanism to specify that a texture will be
used with a pipeline layer without having to create an actual texture.
This patch makes it use that to avoid having an unused texture.
