    gentoo: export the sysvinit RUNLEVEL variable for compatibility reasons
    
    OpenRC 0.4.3+ no longer exports some sysvinit variables, including
    RUNLEVEL.  In order to avoid breaking themes and scripts which still
    rely on this variable being present, we compute a suitable RUNLEVEL
    value using the data available in OpenRC and then export it in
    splash_call().
