This fixes a failing assert in systemd-timesyncd (issue #5913) as it expects the directory /run/systemd/netif/links/ to exist, and nothing in NixOS currently creates it. Also we get a net reduction in our code as rules for /run/utmp and /var/log/journal are also provided by the same upstream file. (cherry picked from commit a278a9224a3c1c5db399d53c86b36a25133b5cda)
