[OE-core] [PATCH 3/3] base: Handle backfilling in anonymous python code, not event handler

[Richard Purdie]

Handling of backfilling is trickier than you'd think. We need this to execute
early enough that the user will see the changes in bitbake -e and other output
yet late enough that the virtclass extensions have changed the tunes before
it executes.

It makes more sense to execute this at anonymous python time now bitbake -e
correctly handles this and that unbreaks multilib corruption of these variables.
