st/mesa: Zero MaxTextureImageUnits for unsupported stages

Browse source 
Mesa core pre-seeds VS/TCS/TES/GS/FS in _mesa_init_constants(..) with
MAX_TEXTURE_IMAGE_UNITS. When a driver does not expose a stage, this
seed leaks into the GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS sum. Drivers
that only expose VS+FS (like etnaviv) overcounted by 96. Zero the
field so the sum reflects only the stages the driver advertises.
