selftests/bpf: remove sockmap + ktls tests

The combination of sockmap and TLS is no longer supported - installing
the TLS ULP on a sockmap socket (and vice versa) is now rejected. Remove
the tests that exercise the combination along with their BPF program;
the file covered nothing but sockmap sockets holding kTLS contexts.
