s3:smbd: make idmap cache persistent for "ldapsam:trusted".

Browse Source 
This stores the mappings found in the idmap cache (which lives
inside gencache). This cache is already read in sid_to_Xid()
and Xid_to_sid() for ldapsam:trusted, this fills the opposite
direction, massively reducing the number of ldap roundtrips
across smbd restarts.
