Add EID as a synonym to SIM status

We can't use EID as keyword to search for it because EID info is located
in the SIM status dialog in which it's not searchable. EID is added as a
synonym of SIM status to support its search result.

Fixes: 133801685
Test: Settings > Search settings > type "eid"
      then will show "SIM status" search result
