    tests: Fix build if TIOCSTI is not defined
    
    Some downstream projects (e.g. ElectroBSD) have removed the TIOCSTI
    
    We already have some components (such as mail and tcsh) that build
    without TIOCSTI defined.  This is (existing portability support in those
    projects.
    
    Simplify things for downstreams by extending this approach to this
    additional TIOCSTI user.
