Include host triple test modules in ResolvedPackage (#7493)

Modified `ResolvedModule` build triples were not reflected in
`ResolvedPackage`, which excluded those modules from the build graph.

Verified manually with `swift-foundation` and `swift-testing` packages.
More comprehensive automated tests will be included in a future PR.

Resolves #7479.

(cherry picked from commit b9eb3c1)
