Centralize retrieving the "parent" build configuration

If a step is part of a build configuration, that is used, but many steps
can be used as part of a deploy configuration.
In that case the active build configuration of the step's target must be
used, and that logic was duplicated many times.
Instead, let BuildStep::buildConfiguration take care of that logic. For
steps that are not offered for deploy configurations there is no
semantic difference, and for the others this removes code duplication.
