    Fix assertion failure if server won't start a shell.
    
    In the recent refactoring, when I rewrote the loop in the SSH-2
    connection layer startup which tries the primary and then the fallback
    command, I failed to reproduce a subtlety of the previous code, namely
    that if CONF_remote_cmd2 holds the empty string, we don't even look
    for CONF_ssh_subsys2. This is because no application other than pscp
    will have set the latter, and looking it up when it's absent triggers
    an assertion failure in conf.c.
