security/tlsc: Add new port

Tlsc is a little BSD-licensed daemon that allows to connect non-TLS
clients to TLS-enabled services.

It's kept simple, so uses all-standard options for TLS and doesn't
implement anything else (like e.g. STARTTLS or doing service-side).

Approved by:	tcberner (mentor, implicit)

+A simple socket proxy for connecting to TLS-enabled services.

+This daemon will listen on sockets (typically on localhost) and forward
+connecting clients to some remote host, adding TLS encryption.
+
+It does the job in the simplest possible way, using all-standard options.
