systemd: fix systemd-tmpfiles ACL issues
On systems where /var/log is not a volatile systemd-tmpfiles creates duplicate ACL entries. This causes systemd-tmpfiles service to fail. Also quietly ignore ACL settings on filesystems that don't support ACLs. Backport the fixes from systemd master to fix these issues.
