package/strongswan: security bump to version 5.9.11

Fix CVE-2023-26463: strongSwan 5.9.8 and 5.9.9 potentially allows remote
code execution because it uses a variable named "public" for two
different purposes within the same function. There is initially
incorrect access control, later followed by an expired pointer
dereference. One attack vector is sending an untrusted client
certificate during EAP-TLS. A server is affected only if it loads
plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS,
EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10.
