refactor(nix/buildkite): use attr path over target drv in mkBuild* r/7629

mkBuild* is independent of the target abstraction, we can just use
attribute paths. That is useful because we'll want to reuse that code in
order to avoid building derivations (apart from unavoidable IfD) during
pipeline construction for extraSteps.

Breaking Change for mkBuildExpr and mkBuildCommand.
