Hm... As the CI configuration is now requesting stress-ng it seems right
that it is pre-installed by the CI image.

OTOH I hate those loose dependencies. Maybe the (lib)evl test package
should pull it in instead? So that the dependency is handled at package
level. Someone else might like to install the test package and get all
dependencies accordingly.

To solve that properly it might make sense to make stress-ng the default
stressor. That would allow the packaging to properly depend on it,
instead of only "suggest" stress-ng.
