panfrost: Stop lowering cs derived sysvals in glsl

Mali GPUs have native gl_GlobalInvocationID support, so we don't want
it to be lowered.

Although we do want to lower gl_LocalInvocationIndex, the single CAP
doesn't allow for choosing what to lower. We've already told NIR to do
the lowering instead, so just disable the GLSL-level lowering.
