    build: bump jansson to 2.7 or newer
    
    RHEL 7.4 has jansson 2.10. Let's bump the minimum so that we could drop
    an ugly workaround for a bug in previous versions.
    
    If someone needs to build the connection editor for an older system,
    they can just easily disable the advanced Team editor.
