rustbuild: fix dist-analysis with full bootstrap disabled

Really fixes #38734, per discussion in #38752 which was solving the underlying problem the wrong way.

This just mirrors the [similar logic] in documentation building as suggested, that just takes the stage1 compiler artifacts instead in case of non-full-bootstrap builds. Actually copying the artifacts around seems to be unnecessary.
