Fix JSON-mode output for !config_stats and/or !config_prof cases.

These bugs were introduced by 0ba5b9b6189e16a983d8922d8c5cb6ab421906e8
(Add "J" (JSON) support to malloc_stats_print().), which was backported
as b599b32280e1142856b0b96293a71e1684b1ccfb (with the same bugs except
the inapplicable "metatata" misspelling) and first released in 4.3.0.
