[CI] add test to check libFoundation.so & co are not linked to the bi… (#441)

This adds a test in the `integration_test.yml` workflow to verify that `libFoundation.so`, `libFoundationInternationalization.so`, and `lib_FoundationICU.so` and not linked the the function binary. This is a follow up from the work make by @t089 to ensure that we don't accidentally link Foundation again in the future.
