config.c: remove config_reader from configsets 

Remove the last usage of "struct config_reader" from configsets by
copying the "kvi" arg instead of recomputing "kvi" from
config_reader.source. Since we no longer need to pass both "struct
config_reader" and "struct config_set" in a single "void *cb", remove
"struct configset_add_data" too.
