In a FreeBSD jail devfs may not expose /dev/dri/card* even though the hw.dri.* sysctl subtree is readable. Add a sysctl-based enumeration like the one for input devices. hw.dri only has entries for primary nodes (no render nodes), and the index N maps directly to the /dev/dri/cardN path that drm-kmod creates, so no type filtering or path translation is needed. Refactor the common OID tree-walk into enumerate_sysctl_units() to avoid duplication with udev_dev_enumerate_evdev_sysctl.
