At run time, /run and /tmp get overmounted with a tmpfs, so anything that is there becomes inaccessible. Scripts in the fakeroot environment could call tools preparing the early environment, leaving traces in /run or /tmp. For example, mkusers might create home directories in /run: openssh sets the sshd home directory to /run/sshd, so mkusers creates it. But since a tmpfs is mounted over it, it doesn't exist at runtime, so the openssh service creates it at startup (and deletes it when the service is stopped). In addition, packages or rootfs overlay may leave things there as well. Those may actually pose a runtime problem because the created file or directory is missing - or it may not be a problem because the package creates the missing files/directories on startup. In this situation, it's better not to have them in the rootfs image (because they're not functional anyway), but it's good to leave them in TARGET_DIR to make it easier to debug the situation. Therefore, remove the contents of /run and /tmp in the fakeroot environment after ROOTFS_PRE_GEN_HOOKS, so they are still left in TARGET_DIR.
