Allow linear tiling when optimal requested with sysmem

We want ImagePipe2 to be able to import both linear and optimal
textures, so whenever optimal tiling is requested we should also allow
linear.  Linear tilings support all operations the optimal tilings do,
so this shouldn't break anything. Sysmem should still prefer optimal
tilings if those are supported.
