    batman-adv: do not add loop detection mac addresses to global tt
    
    This change has been made for local TT already, add another one for
    global TT - but only for temporary entries (aka speedy join), to prevent
    inconsistencies between local and global tables in case an older
    batman-adv version is still announcing those entries from its local
    table.
