Unmention/don't explain SSL, drop 9y old "ssl" keyword/deprecation warning

Switch "ssl" to "tls" in relayd.conf(5) if you haven't done so in the last
ten years, "ssl" is now an error.

Say "TLS" not "SSL/TLS" and drop the primer in the TLS RELAYS section.

OK benno

don't put options in here that should not be needed in the majority of
cases and will just be copied by users without thinking.

Since a while relayd switched from the TLS session cache to using only TLS
session tickets instead. Adjust example relayd.conf file.
From Matt Schwartz, reminded by jmc@ OK deraadt@

Change the keyword "ssl" to "tls" to reflect reality since we
effectively disabled support for the SSL protocols. SSL remains a
common term describing SSL/TLS, there is some controvery about this
change, and the name really doesn't matter, but I feel confident about
it now.

OK benno@, with input from tedu@

Remove SSLv2 and SSLv3 references from the example relayd.conf and the
relevant example snippet in the relayd.conf(5) man page.

Change the default SSL protocols in the example file/man page to
"no tlsv1.0" (suggested by sthen@), which will enable the TLSv1.1
and TLSv1.2 protocols only.
