Rusty Russell e11b35cb3a common/memleak: implement callback arg for dump_memleak.
This makes it easier to use outside simple subds, and now lightningd can
simply dump to log rather than returning JSON.

JSON formatting was a lot of work, and we only did it for lightningd, not for
subdaemons.  Easier to use the logs in all cases.
