bitbake: 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.
