ssh: Reduce the renegotiation limit in test with OpenSSH client
in ssh_to_openssh_SUITE:erlang_server_openssh_client_renegotiate/1 The reason is that it seems that on some small machines we get an out-of-memory exception if the limit is to high. This is probably because a chunk of data larger than the limit is piped from a file into the OpenSSH runing in a shell in a port.
