st/dri: Don't expose sRGB formats to clients
Though the SARGB8888 format is used internally through its FourCC value,
it is not a real format as defined by drm_fourcc.h; it cannot be used
with KMS or other interfaces expecting drm_fourcc.h format codes.
Ensure we don't advertise it through the dmabuf format/modifier query
interfaces, preventing us from tripping over an assert.
