panfrost: Don't lie about Z/S formats

Only Z24S8 is properly supported right now, so let's be careful. Fixes a
number of issues relating to improper Z/S handling. The most obvious is
depth buffers with incorrect strides, which manifests in truly bizarre
ways and can happen commonly with FBOs.

Fixes WebGL (Aquarium runs, etc).
