sched/eevdf: Fix rb augmented with multi fields

Browse source

The eevdf rb tree maintains 3 augmented fields but only one is currently
copied when balancing the tree.

Add a more generic define that can be used when there are several augmented
fields. In this case, we provide a function that takes care of copying all
fields.
