[CI] RHEL 8 test failures

[christophfroehlich]

On RHEL 8 we have strange warnings by pluginlib with failing tests afterwards.

Warning: class_loader.impl: SEVERE WARNING!!! A namespace collision has occurred with plugin factory for class mock_components::GenericSystem. New factory will OVERWRITE existing one. This situation occurs when libraries containing plugins are directly linked against an executable (the one running right now generating this message). Please separate plugins out into their own library or just don't link against the library and use either class_loader::ClassLoader/MultiLibraryClassLoader to open.

This can be reproduced from humble branch using act gh act pull_request -W .github/workflows/humble-rhel-semi-binary-build.yml
