turnip: Disable tiling on 1D images.

Browse source 
If we know the height is 1, then it would be a waste to align each
miplevel to tile height.  For non-mipmapped textures, it doesn't save us
memory (since you still align to 4 on the last miplevel), but it should be
better cache locality by not loading those unused lines.

Incidentally, this gets us some more coverage of swap != WZYX cases in CTS
tests, which often use optimal tiling without also testing linear.
