udev: export tags of "dead" device nodes to /run/udev/static_node-tags/
Based on a patch by Kay Sievers.
A tag is exported at boot as a symlinks to the device node in the folder
/run/udev/static_node-tags/<tagname>/, if the device node exists.
These tags are cleaned up by udevadm info --cleanup-db, but are otherwise
never removed.
