/dev/dri/* is not the cause of any issue here, and I guess access is already provided.
AFAIR adding /dev/dri/* doesn't fix the issue on unity8.
The question is whether "/sys/devices/pci[0-9]*/**/config r," is being provided by unity8 to all apps or not, if not then adding that in each app will be only option
