Retire OpenSSL 1.0.2 interop

Now that the OpenSSL 1.0.2 port is gone, there's no need to keep the
interop tests anymore. anton's and bluhm's regress tests will switch
to testing interoperability with OpenSSL 3.0.

 Test TLS interoperability between LibreSSL and OpenSSL.
 
 Implement simple SSL client and server in C.  Create six binaries

+by linking them with LibreSSL or OpenSSL 1.1 or OpenSSL 3.0.  This
 way API compatibility is tested.
 
 To self test each SSL library, connect client with server.  Check
 that the highest available TLS version is selected.  LibreSSL TLS
 1.3 check has to be enabled when the feature becomes available.
 
-Currently OpenSSL 1.0.2p and OpenSSL 1.1.1 from ports are used.  As
-soon as LibreSSL supports TLS 1.3, it should be used automatically
-when netcat is communicating with OpenSSL 1.1.
-
 Connect and accept with netcat to test protocol compatibility with
 libtls.  Test TLS session reuse multiple times with different library
 combinations.  The cert subdir is testing all combinations of
