This is a problem in all other Fedoras and most probably in RHEL7 too (needs investigation) Probably related to the other issue I can see in the logs about the unlink when calling
# systemctl restart systemd-journald systemd-journald-dev-log.socket
results in
# audit2allow

Please, add also this one.
