net/sslh: update to 1.22c

Most notably, sslh now supports UDP and, thus, QUIC and Teamspeak.
For the release announcement see:
https://lists.rutschle.net/mailman/archives/sslh/2021-August/000744.html

While at it:
- Give the sample configuration file @sample treatment.
- Install all remaining example configuration files as EXAMPLES.
- Make the EXAMPLES knob actually work as intended by not installing
  corresponding files when it's off.
- Refresh pkg-descr.

-sslh accepts HTTPS, SSH, OpenVPN, tinc and XMPP connections on the same port.
-This makes it possible to connect to any of these servers on port 443 while
-still serving HTTPS on that port.
+sslh accepts connections on specified ports, and forwards them further based
+on tests performed on the first data packet sent by the remote client.
 
-WWW: http://www.rutschle.net/tech/sslh.shtml
+Probes for HTTP, TLS/SSL (including SNI and ALPN), SSH, OpenVPN, tinc, XMPP,
+SOCKS5, are implemented, and any other protocol that can be tested using a
+regular expression, can be recognised. A typical use case is to allow serving
+several services on port 443 (e.g. to connect to SSH from inside a corporate
+firewall, which almost never block port 443) while still serving HTTPS on
+that port.
+
+Hence sslh acts as a protocol demultiplexer, or a switchboard. With the SNI
+and ALPN probe, it makes a good front-end to a virtual host farm hosted
+behind a single IP address.
+
+sslh has the bells and whistles expected from a mature daemon: privilege and
+capabilities dropping, inetd support, systemd support, transparent proxying,
+chroot, logging, IPv4 and IPv6, TCP and UDP, a fork-based and a select-based
+model, and more.
