passdb: Cache output from pdb_[ug]id_to_sid
A customer complained that after upgrading to Samba 4.0 fileserver
its LDAP server was flooded with uid2sid and gid2sid request for id
0. With 4.0 we do a lot more user-space ACL checking which involves
uid2sid/gid2sid. This caches the corresponding results.
