    runqueue: Filter out multiconfig dependencies from BB_TASKDEPDATA
    
    The consumers of BB_TASKDEPDATA in OE metadata can't cope with multiconfig
    dependencies. The choice is either to start adding code to each of them to
    filter out multiconfig dependencies, or do this at source.
    
    After consideration we've decided to do this at source as doing otherwise
    is code duplication and error prone and in any case we've looked at, they
    don't make sense.
