ci/unit-tests: enable dlopen note verification tests

Enable the `dlopen` unit test suite in GitHub Actions, except for the
following configurations where linker garbage collection (`--gc-sections`)
or dead-code elimination fails to drop unused dlopen symbols:

- ppc64le (both GCC and Clang)
- s390x (GCC only)
- Sanitizer-enabled setups
