rules: load path_id on DRM devices

The path_id-builtin provides useful unique aliases for DRM devices. If we
want to configure DRM render-nodes for compositors, we want to avoid
storing the whole sys-path in configuration files. Hence, allow users to
store the short PATH_ID instead.

Load path_id-builtin unconditionally on DRM devices now to always provide
this alias.
