Return shared Emergency Country Iso for Multi-sim country iso

In multi-sim, some vendor may only notify the emergency network
info only through one of the IRadio slots, so that the emergency country
info of the other IRadio slots are missing and the emergency number list
from the database cannot be cached based on the country. To solve this,
we need the share the emergency network country to other slots if those
slots are not registrated with the emergency network.
