    libide/foundry: allow setting locality for unit tests
    
    This allows running the unit tests in either the runtime or pipeline
    environments. This can be a bit more convenient than spinning up a
    fake display for unit tests.
    
    We do want peope to be aware that unit tests should be automated in the
    CI, and therefore display access is not necessarily a given.
