zink: do not report SSBOs as halfway supported

Browse source 
We don't support SSBOs yet, as we don't expose the
PIPE_CAP_SHADER_BUFFER_OFFSET_ALIGNMENT-cap. But the gallium
state-tracker's limit-calculation gets confused by this half-way
support, and ends up thinking we can support atomics, which we
don't support yet either.

So let's not confuse the state-tracker here, and let's introduce this
again when SSBOs are actually supported.
