    lttng-tools: add systemd support
    
    Add systemd service file of lttng-tools from Fedora
    
    ftp://fr2.rpmfind.net/linux/fedora/linux/development/rawhide
    /Everything/source/tree/Packages/l/lttng-tools-2.10.5-1.fc29.src.rpm
    
    It requires kernel configs CONFIG_STAGING and CONFIG_LTTNG2 to be set.
    But linux-yocto doesn't meet the requirement. So disable the service by
    default.
