rules: add persistent by-path drm rules (#5337)
Create persistent symlinks for DRM devices, ex: /dev/dri/by-path/pci-0000:00:02.0-card -> /dev/dri/card1 /dev/dri/by-path/pci-0000:00:02.0-render -> /dev/dri/renderD129 etc... This allows to configure DRM device usage with stable paths. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com>
