Re-add uaccess tag for /dev/dri/renderD*

Setting an access mode != 0666 is explicitly supported via -Dgroup-render-mode
In such a case, re-add the uaccess tag.

This is basically the same change that was done for /dev/kvm in
commit fa53e24130af3a389573acb9585eadbf7192955f and
ace5e3111c0b8d8bfd84b32f2c689b0a4d92c061
and partially reverts the changes from
