    systemd: Use app- prefix for systemd slice
    
    To avoid confusion, we have updated the systemd specification to use
    app.slice rather than apps.slice. Update the use here accordingly.
    
    This change is in no way urgent as other software is not using the
    conventions yet.
    
    See https://github.com/systemd/systemd/pull/15647
    
    Closes: #260
