    power: Use logind to discover CanHibernate
    
    The upower functionality is deprecated and will return an
    error unless upower is built with --enable-deprecated.
    
    The function is also not defined unless the application defines
    UPOWER_ENABLE_DEPRECATED, which g-c-c does not do, and the build
    system currently does not enable the warning (or error) about this.
