revert(published): keep source-mapped "." export for bundler plugins

The exports rewrite in 8f0b64f was unrelated scope creep for this PR
and broke in-repo TypeScript resolution (tests import these packages
and resolved to a missing dist/*.d.ts), causing Linting/Unit tests to
fail in CI. This PR only needs to add the @datadog/apps-backend
runtime wiring in backend/shared.ts and backend/virtual-entry.ts.
