refactor: opus test_package

[ErniGH]

Simplify the test_package in according to our policies:

• Write the minimal test that tests the package (the compiler can find the correct includes, the static linker can resolve
  symbols, the runtime linker can resolve symbols).
• Do not perform heavy logic in CI.
• Remove binary blob - these have not been allowed anywhere in the repository for a while now, it's time to drop them where they exist
