- Set database type for address_verify_map and postscreen_cache_map
to lmdb (btree requires Berkeley DB)
- Set default database type to lmdb and fix update_postmaps script
- Use variable substition instead of sed to remove .db suffix and
substitute hash: for lmdb: in /etc/postfix/master.cf as well.
Check before substitution if there is something to do (to keep
rpmcheck happy).
