[gnome-logs/wip/larsu/listmodel] eventviewlist: don't use g_str_match_string()

    eventviewlist: don't use g_str_match_string()
    
    Not searching inside words is a regression. ASCII alternates probably
    don't buy us that much anyway, because log messages tend to be ASCII
    already. (See last commit.)
