material: set ->layer_index on new layers for unit0

Browse Source 
We were mistakenly only initializing layer->layer_index for new layers
associated with texture units > 0. This had gone unnoticed because
normally layers associated with texture unit0 have a layer index of 0
too. Mutter was hitting this issue because it was initializing layer 1
before layer 0 for one of its materials so layer 1 was temporarily
associated with texture unit 0.
