[Buildroot] [PATCH] package/systemd: security bump to version 247.9

[Peter Korsgaard]

Fixes the following security issues:

- CVE-2020-13529: An exploitable denial-of-service vulnerability exists in
  Systemd 245.  A specially crafted DHCP FORCERENEW packet can cause a
  server running the DHCP client to be vulnerable to a DHCP ACK spoofing
  attack.  An attacker can forge a pair of FORCERENEW and DCHP ACK packets
  to reconfigure the server.

- CVE-2021-33910: Denial of Service (Stack Exhaustion) in systemd (PID 1)
  https://blog.qualys.com/vulnerabilities-threat-research/2021/07/20/cve-2021-33910-denial-of-service-stack-exhaustion-in-systemd-pid-1

Update hash of README for a change of IRC network:
-        #systemd on irc.freenode.org
+        #systemd on irc.libera.chat
